Square of 131
The product of multiplying an integer by itself is the square of a number. Square is used in programming, calculating areas, and so on. In the topic, we will discuss the square of 131.
What is the Square of 131
The square of a number is the product of the number itself. The square of 131 is 131 × 131. The square of a number always ends in 0, 1, 4, 5, 6, or 9. We write it in math as 131², where 131 is the base and 2 is the exponent.
The square of a positive and a negative number is always positive. For example, 5² = 25; -5² = 25.
The square of 131 is 131 × 131 = 17161. Square of 131 in exponential form: 131² Square of 131 in arithmetic form: 131 × 131
How to Calculate the Value of Square of 131
The square of a number is multiplying the number by itself. So let’s learn how to find the square of a number. These are the common methods used to find the square of a number.
- By Multiplication Method
- Using a Formula
- Using a Calculator
By the Multiplication method
In this method, we will multiply the number by itself to find the square. The product here is the square of the number. Let’s find the square of 131.
Step 1: Identify the number. Here, the number is 131.
Step 2: Multiplying the number by itself, we get, 131 × 131 = 17161. The square of 131 is 17161.
Using a Formula (a²)
In this method, the formula, a² is used to find the square of the number. Where a is the number.
Step 1: Understanding the equation Square of a number = a² a² = a × a
Step 2: Identifying the number and substituting the value in the equation. Here, ‘a’ is 131. So: 131² = 131 × 131 = 17161
By Using a Calculator
Using a calculator to find the square of a number is the easiest method. Let’s learn how to use a calculator to find the square of 131.
Step 1: Enter the number in the calculator. Enter 131 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×). That is 131 × 131
Step 3: Press the equal button to find the answer. Here, the square of 131 is 17161.
Tips and Tricks for the Square of 131 Tips and tricks make it easy for students to understand and learn the square of a number. To master the square of a number, these tips and tricks will help students. The square of an even number is always an even number. For example, 6² = 36 The square of an odd number is always an odd number. For example, 5² = 25 The last digit of the square of a number is always 0, 1, 4, 5, 6, or 9. If the square root of a number is a fraction or a decimal, then the number is not a perfect square. For example, √1.44 = 1.2 The square root of a perfect square is always a whole number. For example, √144 = 12.
Common Mistakes to Avoid When Calculating the Square of 131
Mistakes are common among kids when doing math, especially when it is finding the square of a number. Let’s learn some common mistakes to master the squaring of a number.
Mistake 1
Calculation errors:
Calculation errors mostly happen when students skip the steps or else by swapping the digits. To avoid it, students should double-check the answer. They can double-check by finding the square root of the solution they found.
For example, the square of 25 is 625, and the square root of 625 is ±25.
Mistake 2
Errors will be using the formula.
The formula to find the square of the number is a². Instead, students may use 131² with (1 + 3 + 1)² or (130 + 1)². So students should check and use the correct formula and double-check the answers to avoid all the confusion.
Mistake 3
Confusing with square and square root.
Not understanding the concept of square and square root can lead to confusion in students. To avoid it, students should understand the concept that square and square root are inverse operations. The square of 5 is 25 and the square root of 25 is ±5.
Mistake 4
Errors in parentheses.
Ignoring the parentheses when finding the square of a number can lead to errors. So, students should understand parentheses. And do the operations in the correct order to avoid error.
Mistake 5
Not practicing regularly.
Regular practice is required to master the square of a number. So students should do regular practice to avoid errors.
Solved Examples on Square of 131
Problem 1
Find the length of the square, where the area of the square is 17161 cm².
The area of a square = a² So, the area of a square = 17161 cm² So, the length = √17161 = 131. The length of each side = 131 cm
Explanation
The length of a square is 131 cm.
Because the area is 17161 cm², the length is √17161 = 131.
Problem 2
Sarah is planning to tile her square garden of length 131 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full garden?
The length of the garden = 131 feet The cost to tile 1 square foot of the garden = 5 dollars. To find the total cost to tile, we find the area of the garden, Area of the garden = area of the square = a² Here a = 131 Therefore, the area of the garden = 131² = 131 × 131 = 17161. The cost to tile the garden = 17161 × 5 = 85805. The total cost = 85805 dollars
Explanation
To find the cost to tile the garden, we multiply the area of the garden by the cost to tile per foot.
So, the total cost is 85805 dollars.
Problem 3
Find the area of a circle whose radius is 131 meters.
The area of the circle = 53906.28 m²
Explanation
The area of a circle = πr²
Here, r = 131
Therefore, the area of the circle = π × 131²
= 3.14 × 131 × 131
= 53906.28 m².
Problem 4
The area of the square is 17161 cm². Find the perimeter of the square.
The perimeter of the square is 524 cm
Explanation
The area of the square = a²
Here, the area is 17161 cm²
The length of the side is √17161 = 131
Perimeter of the square = 4a
Here, a = 131
Therefore, the perimeter = 4 × 131
= 524.
Problem 5
Find the square of 132.
The square of 132 is 17424
Explanation
The square of 132 is multiplying 132 by 132.
So, the square = 132 × 132 = 17424
