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 920.
Step 1: Identify the number. Here, the number is 920
Step 2: Multiplying the number by itself, we get, 920 × 920 = 846400.
The square of 920 is 846400.
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 920
So: 920² = 920 × 920 = 846400
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 920.

For example, the square of 25 is 625, and the square root of 625 is ±25.
Solved Examples on Square of 920
Problem 1
Find the length of the square, where the area of the square is 846400 cm².
The area of a square = a² So, the area of a square = 846400 cm² So, the length = √846400 = 920. The length of each side = 920 cm
Explanation
The length of a square is 920 cm.
Because the area is 846400 cm², the length is √846400 = 920.
Problem 2
Anna is planning to paint her square wall of length 920 feet. The cost to paint a foot is 5 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 920 feet The cost to paint 1 square foot of wall = 5 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 = 920 Therefore, the area of the wall = 920² = 920 × 920 = 846400. The cost to paint the wall = 846400 × 5 = 4232000. The total cost = 4232000 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 4232000 dollars.
Problem 3
Find the area of a circle whose radius is 920 meters.
The area of the circle = 2,660,320 m²
Explanation
The area of a circle = πr²
Here, r = 920
Therefore, the area of the circle = π × 920² = 3.14 × 920 × 920 = 2,660,320 m².
Problem 4
The area of the square is 846400 cm². Find the perimeter of the square.
The perimeter of the square is 3680 cm
Explanation
The area of the square = a²
Here, the area is 846400 cm²
The length of the side is √846400 = 920
Perimeter of the square = 4a
Here, a = 920
Therefore, the perimeter = 4 × 920 = 3680 cm.
Problem 5
Find the square of 921.
The square of 921 is 848241
Explanation
The square of 921 is multiplying 921 by 921.
So, the square = 921 × 921 = 848241
