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 838.
Step 1: Identify the number. Here, the number is 838.
Step 2: Multiply the number by itself, we get, 838 × 838 = 702,244.
The square of 838 is 702,244.
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: Identify the number and substitute the value in the equation.
Here, ‘a’ is 838.
So: 838² = 838 × 838 = 702,244
By Using a Calculator

Solved Examples on Square of 838
Problem 1
Find the length of the square, where the area of the square is 702,244 cm².
The area of a square = a² So, the area of a square = 702,244 cm² So, the length = √702,244 = 838. The length of each side = 838 cm
Explanation
The length of a square is 838 cm.
Because the area is 702,244 cm², the length is √702,244 = 838.
Problem 2
Alice is planning to tile her square garden of length 838 feet. The cost to tile a foot is 4 dollars. Then how much will it cost to tile the entire garden?
The length of the garden = 838 feet The cost to tile 1 square foot of garden = 4 dollars. To find the total cost to tile, we find the area of the garden, Area of the garden = area of the square = a² Here a = 838 Therefore, the area of the garden = 838² = 838 × 838 = 702,244. The cost to tile the garden = 702,244 × 4 = 2,808,976. The total cost = 2,808,976 dollars
Explanation
To find the cost to tile the garden, we multiply the area of the garden by the cost to tile per foot.
So, the total cost is 2,808,976 dollars.
Problem 3
Find the area of a circle whose radius is 838 meters.
The area of the circle = 2,206,248.77 m²
Explanation
The area of a circle = πr²
Here, r = 838
Therefore, the area of the circle = π × 838² = 3.14 × 838 × 838 = 2,206,248.77 m².
Problem 4
The area of the square is 702,244 cm². Find the perimeter of the square.
The perimeter of the square is 3,352 cm.
Explanation
The area of the square = a²
Here, the area is 702,244 cm²
The length of the side is √702,244 = 838
Perimeter of the square = 4a
Here, a = 838
Therefore, the perimeter = 4 × 838 = 3,352 cm.
Problem 5
Find the square of 839.
The square of 839 is 703,921.
Explanation
The square of 839 is multiplying 839 by 839.
So, the square = 839 × 839 = 703,921.
