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 210.
Step 1: Identify the number. Here, the number is 210.
Step 2: Multiplying the number by itself, we get, 210 × 210 = 44100.
The square of 210 is 44100.
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 210.
So: 210² = 210 × 210 = 44100
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 210.

For example, the square of 210 is 44100, and the square root of 44100 is ±210.
Solved Examples on Square of 210
Problem 1
Find the length of the square, where the area of the square is 44100 cm².
The area of a square = a² So, the area of a square = 44100 cm² So, the length = √44100 = 210. The length of each side = 210 cm.
Explanation
The length of a square is 210 cm.
Because the area is 44100 cm² the length is √44100 = 210.
Problem 2
Sarah wants to tile her square patio of length 210 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full patio?
The length of the patio = 210 feet The cost to tile 1 square foot of the patio = 5 dollars. To find the total cost to tile, we find the area of the patio, Area of the patio = area of the square = a² Here a = 210 Therefore, the area of the patio = 210² = 210 × 210 = 44100. The cost to tile the patio = 44100 × 5 = 220500. The total cost = 220500 dollars.
Explanation
To find the cost to tile the patio, we multiply the area of the patio by the cost to tile per foot.
So, the total cost is 220500 dollars.
Problem 3
Find the area of a circle whose radius is 210 meters.
The area of the circle = 138544.64 m²
Explanation
The area of a circle = πr²
Here, r = 210
Therefore, the area of the circle = π × 210² = 3.14 × 210 × 210 = 138544.64 m².
Problem 4
The area of the square is 44100 cm². Find the perimeter of the square.
The perimeter of the square is 840 cm.
Explanation
The area of the square = a²
Here, the area is 44100 cm²
The length of the side is √44100 = 210
Perimeter of the square = 4a
Here, a = 210
Therefore, the perimeter = 4 × 210 = 840 cm.
Problem 5
Find the square of 211.
The square of 211 is 44521.
Explanation
The square of 211 is multiplying 211 by 211.
So, the square = 211 × 211 = 44521.
