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 331.
Step 1: Identify the number. Here, the number is 331.
Step 2: Multiply the number by itself, we get, 331 × 331 = 109,561.
The square of 331 is 109,561.
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 331.
So: 331² = 331 × 331 = 109,561
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 331.
Step 1: Enter the number in the calculator. Enter 331 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×). That is 331 × 331
Step 3: Press the equal button to find the answer. Here, the square of 331 is 109,561.
Tips and Tricks for the Square of 331
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 331
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 331² with (3+3+1)² or (330+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 errors.
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 331
Problem 1
Find the length of the square, where the area of the square is 109,561 cm².
The area of a square = a²
So, the area of a square = 109,561 cm²
So, the length = √109,561 = 331.
The length of each side = 331 cm
Explanation
The length of a square is 331 cm. Because the area is 109,561 cm², the length is √109,561 = 331.
Problem 2
Lisa is planning to tile her square floor of length 331 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full floor?
The length of the floor = 331 feet
The cost to tile 1 square foot of floor = 5 dollars.
To find the total cost to tile, we find the area of the floor.
Area of the floor = area of the square = a²
Here a = 331
Therefore, the area of the floor = 331² = 331 × 331 = 109,561.
The cost to tile the floor = 109,561 × 5 = 547,805.
The total cost = 547,805 dollars
Explanation
To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot. So, the total cost is 547,805 dollars.
Problem 3
Find the area of a circle whose radius is 331 meters.
The area of the circle = 344,360.78 m²
Explanation
The area of a circle = πr²
Here, r = 331
Therefore, the area of the circle = π × 331² = 3.14 × 331 × 331 = 344,360.78 m².
Problem 4
The area of the square is 109,561 cm². Find the perimeter of the square.
The perimeter of the square is 1,324 cm.
Explanation
The area of the square = a²
Here, the area is 109,561 cm²
The length of the side is √109,561 = 331
Perimeter of the square = 4a
Here, a = 331
Therefore, the perimeter = 4 × 331 = 1,324.
Problem 5
Find the square of 332.
The square of 332 is 110,224
Explanation
The square of 332 is multiplying 332 by 332.
So, the square = 332 × 332 = 110,224
