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 239
Step 1: Identify the number. Here, the number is 239
Step 2: Multiplying the number by itself, we get, 239 × 239 = 57121.
The square of 239 is 57121.
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 239
So: 239² = 239 × 239 = 57121
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 239.
Step 1: Enter the number in the calculator Enter 239 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 239 × 239
Step 3: Press the equal to button to find the answer
Here, the square of 239 is 57121.
Tips and Tricks for the Square of 239
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 239
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 239² with (2+3+9)² or (230+9)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 239
Problem 1
Find the length of the square, where the area of the square is 57121 cm².
The area of a square = a² So, the area of a square = 57121 cm² So, the length = √57121 = 239. The length of each side = 239 cm
Explanation
The length of a square is 239 cm.
Because the area is 57121 cm² the length is √57121 = 239.
Problem 2
Alice is planning to paint her square mural of length 239 inches. The cost to paint an inch is 2 dollars. Then how much will it cost to paint the full mural?
The length of the mural = 239 inches The cost to paint 1 square inch of mural = is 2 dollars. To find the total cost to paint, we find the area of the mural, Area of the mural = area of the square = a² Here a = 239 Therefore, the area of the mural = 239² = 239 × 239 = 57121. The cost to paint the mural = 57121 × 2 = 114242. The total cost = 114242 dollars
Explanation
To find the cost to paint the mural, we multiply the area of the mural by the cost to paint per inch.
So, the total cost is 114242 dollars.
Problem 3
Find the area of a circle whose radius is 239 meters.
The area of the circle = 179,032.89 m²
Explanation
The area of a circle = πr²
Here, r = 239
Therefore, the area of the circle = π × 239² = 3.14 × 239 × 239 = 179,032.89 m².
Problem 4
The area of the square is 57121 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 57121 cm²
The length of the side is √57121 = 239
Perimeter of the square = 4a
Here, a = 239
Therefore, the perimeter = 4 × 239 = 956.
Problem 5
Find the square of 240.
The square of 240 is 57600
Explanation
The square of 240 is multiplying 240 by 240.
So, the square = 240 × 240 = 57600
