Step 2: Multiply the number by itself using the multiplication button (×) That is 238 × 238
Step 3: Press the equal to button to find the answer
Here, the square of 238 is 56,644.
Tips and Tricks for the Square of 238
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 238
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 238² with (23 + 8)² or (230 + 8)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 238
Problem 1
Find the length of the square, where the area of the square is 56,644 cm².
The area of a square = a² So, the area of a square = 56,644 cm² So, the length = √56,644 = 238. The length of each side = 238 cm
Explanation
The length of a square is 238 cm.
Because the area is 56,644 cm², the length is √56,644 = 238.
Problem 2
Sarah is planning to paint her square wall of length 238 feet. The cost to paint a foot is 4 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 238 feet The cost to paint 1 square foot of wall = 4 dollars. To find the total cost to paint, we find the area of the wall, Area of the wall = area of the square = a² Here a = 238 Therefore, the area of the wall = 238² = 238 × 238 = 56,644. The cost to paint the wall = 56,644 × 4 = 226,576. The total cost = 226,576 dollars
Explanation
To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot.
So, the total cost is 226,576 dollars.
Problem 3
Find the area of a circle whose radius is 238 meters.
The area of the circle = 177,591.76 m²
Explanation
The area of a circle = πr²
Here, r = 238
Therefore, the area of the circle = π × 238² = 3.14 × 238 × 238 = 177,591.76 m².
Problem 4
The area of the square is 56,644 cm². Find the perimeter of the square.
The perimeter of the square is 952 cm.
Explanation
The area of the square = a²
Here, the area is 56,644 cm²
The length of the side is √56,644 = 238
Perimeter of the square = 4a
Here, a = 238
Therefore, the perimeter = 4 × 238 = 952.
Problem 5
Find the square of 239.
The square of 239 is 57,121.
Explanation
The square of 239 is multiplying 239 by 239.
So, the square = 239 × 239 = 57,121
