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 115
Step 1: Identify the number. Here, the number is 115
Step 2: Multiplying the number by itself, we get, 115 × 115 = 13225.
The square of 115 is 13225.
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 115
So: 115² = 115 × 115 = 13225
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 115.

For example, the square of 25 is 625, and the square root of 625 is ±25.
Solved Examples on Square of 115
Problem 1
Find the length of the square, where the area of the square is 13225 cm².
The area of a square = a²
So, the area of a square = 13225 cm²
So, the length = √13225 = 115.
The length of each side = 115 cm
Explanation
The length of a square is 115 cm. Because the area is 13225 cm² the length is √13225 = 115.
Problem 2
Sarah is planning to wallpaper her square room of length 115 feet. The cost to wallpaper a foot is 4 dollars. Then how much will it cost to wallpaper the full room?
The length of the room = 115 feet
The cost to wallpaper 1 square foot of wall = 4 dollars.
To find the total cost to wallpaper, we find the area of the room,
Area of the room = area of the square = a²
Here a = 115
Therefore, the area of the room = 115² = 115 × 115 = 13225.
The cost to wallpaper the room = 13225 × 4 = 52900.
The total cost = 52900 dollars
Explanation
To find the cost to wallpaper the room, we multiply the area of the room by cost to wallpaper per foot. So, the total cost is 52900 dollars.
Problem 3
Find the area of a circle whose radius is 115 meters.
The area of the circle = 41548.75 m²
Explanation
The area of a circle = πr² Here, r = 115 Therefore, the area of the circle = π × 115² = 3.14 × 115 × 115 = 41548.75 m².
Problem 4
The area of the square is 13225 cm². Find the perimeter of the square.
The perimeter of the square is 460 cm.
Explanation
The area of the square = a² Here, the area is 13225 cm² The length of the side is √13225 = 115 Perimeter of the square = 4a Here, a = 115 Therefore, the perimeter = 4 × 115 = 460.
Problem 5
Find the square of 116.
The square of 116 is 13456.
Explanation
The square of 116 is multiplying 116 by 116. So, the square = 116 × 116 = 13456.
