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 531
Step 1: Identify the number. Here, the number is 531
Step 2: Multiplying the number by itself, we get, 531 × 531 = 281,961.
The square of 531 is 281,961.
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 531 So: 531² = 531 × 531 = 281,961
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 531.
Step 1: Enter the number in the calculator Enter 531 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 531 × 531
Step 3: Press the equal to button to find the answer Here, the square of 531 is 281,961.
Tips and Tricks for the Square of 531
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 531
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.
Solved Examples on Square of 531
Problem 1
Find the length of the square, where the area of the square is 281,961 cm².
The area of a square = a²
So, the area of a square = 281,961 cm²
So, the length = √281,961 = 531.
The length of each side = 531 cm
Explanation
The length of a square is 531 cm. Because the area is 281,961 cm² the length is √281,961 = 531.
Problem 2
Mary is planning to paint her square garden wall of length 531 feet. The cost to paint a foot is 2 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 531 feet
The cost to paint 1 square foot of wall = 2 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 = 531 Therefore, the area of the wall = 531² = 531 × 531 = 281,961.
The cost to paint the wall = 281,961 × 2 = 563,922.
The total cost = 563,922 dollars
Explanation
To find the cost to paint the wall, we multiply the area of the wall by cost to paint per foot. So, the total cost is 563,922 dollars.
Problem 3
Find the area of a circle whose radius is 531 meters.
The area of the circle = 885,310.29 m²
Explanation
The area of a circle = πr²
Here, r = 531
Therefore, the area of the circle = π × 531² = 3.14 × 531 × 531 = 885,310.29 m².
Problem 4
The area of the square is 281,961 cm². Find the perimeter of the square.
The perimeter of the square is 2,124 cm
Explanation
The area of the square = a²
Here, the area is 281,961 cm²
The length of the side is √281,961 = 531
Perimeter of the square = 4a
Here, a = 531
Therefore, the perimeter = 4 × 531 = 2,124.
Problem 5
Find the square of 532.
The square of 532 is 283,024
Explanation
The square of 532 is multiplying 532 by 532.
So, the square = 532 × 532 = 283,024
