Solved Examples on Square of 939
Problem 1
Find the length of the square, where the area of the square is 881721 cm².
The area of a square = a²
So, the area of a square = 881721 cm²
So, the length = √881721 = 939.
The length of each side = 939 cm
Explanation
The length of a square is 939 cm.
Because the area is 881721 cm², the length is √881721 = 939.
Problem 2
Tom is planning to paint his square wall of length 939 feet. The cost to paint a foot is 3 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 939 feet
The cost to paint 1 square foot of wall = 3 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 = 939
Therefore, the area of the wall = 939² = 939 × 939 = 881721.
The cost to paint the wall = 881721 × 3 = 2,645,163.
The total cost = 2,645,163 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 2,645,163 dollars.
Problem 3
Find the area of a circle whose radius is 939 meters.
The area of the circle = 2,772,625.14 m²
Explanation
The area of a circle = πr²
Here, r = 939
Therefore, the area of the circle = π × 939² = 3.14 × 939 × 939 = 2,772,625.14 m².
Problem 4
The area of the square is 1396 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 1396 cm²
The length of the side is √1396 = 37
Perimeter of the square = 4a
Here, a = 37
Therefore, the perimeter = 4 × 37 = 148.
Problem 5
Find the square of 940.
The square of 940 is 883600
Explanation
The square of 940 is multiplying 940 by 940.
So, the square = 940 × 940 = 883600
