- By Multiplication Method
- Using a Formula (a2)
- 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 1231.
Step 1: Identify the number. Here, the number is 1231.
Step 2: Multiplying the number by itself, we get, 1231 × 1231 = 1,515,361.
The square of 1231 is 1,515,361.
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 1231
So: 1231² = 1231 × 1231 = 1,515,361
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 1231.
Step 1: Enter the number in the calculator. Enter 1231 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×). That is 1231 × 1231
Step 3: Press the equal to button to find the answer. Here, the square of 1231 is 1,515,361.
Tips and Tricks for the Square of 1231
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 1231
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

For example, the square of 25 is 625, and the square root of 625 is ±25.
Solved Examples on Square of 1231
Problem 1
Find the length of the square, where the area of the square is 1,515,361 cm².
The area of a square = a²
So, the area of a square = 1,515,361 cm²
So, the length = √1,515,361 = 1231.
The length of each side = 1231 cm
Explanation
The length of a square is 1231 cm.
Because the area is 1,515,361 cm², the length is √1,515,361 = 1231.
Problem 2
Alex is planning to tile his square floor of length 1231 feet. The cost to tile a foot is 4 dollars. Then how much will it cost to tile the full floor?
The length of the floor = 1231 feet
The cost to tile 1 square foot of floor = 4 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 = 1231
Therefore, the area of the floor = 1231² = 1231 × 1231 = 1,515,361.
The cost to tile the floor = 1,515,361 × 4 = 6,061,444.
The total cost = 6,061,444 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 6,061,444 dollars.
Problem 3
Find the area of a circle whose radius is 1231 meters.
The area of the circle = 4,760,999.34 m²
Explanation
The area of a circle = πr²
Here, r = 1231
Therefore, the area of the circle = π × 1231² = 3.14 × 1231 × 1231 = 4,760,999.34 m².
Problem 4
The area of the square is 1,515,361 cm². Find the perimeter of the square.
The perimeter of the square is 4,924 cm
Explanation
The area of the square = a²
Here, the area is 1,515,361 cm²
The length of the side is √1,515,361 = 1231
Perimeter of the square = 4a
Here, a = 1231
Therefore, the perimeter = 4 × 1231 = 4,924.
Problem 5
Find the square of 1232.
The square of 1232 is 1,517,824
Explanation
The square of 1232 is multiplying 1232 by 1232.
So, the square = 1232 × 1232 = 1,517,824
