Solved Examples on Square of 756
Problem 1
Find the length of the square, where the area of the square is 571,536 cm².
The area of a square = a²
So, the area of a square = 571,536 cm²
So, the length = √571,536 = 756.
The length of each side = 756 cm
Explanation
The length of a square is 756 cm.
Because the area is 571,536 cm², the length is √571,536 = 756.
Problem 2
Emily is planning to carpet her square living room with a length of 756 feet. The cost to carpet a square foot is 5 dollars. Then how much will it cost to carpet the full room?
The length of the room = 756 feet
The cost to carpet 1 square foot = 5 dollars.
To find the total cost to carpet, we find the area of the room, Area of the room = area of the square = a²
Here a = 756
Therefore, the area of the room = 756² = 756 × 756 = 571,536.
The cost to carpet the room = 571,536 × 5 = 2,857,680.
The total cost = 2,857,680 dollars
Explanation
To find the cost to carpet the room, we multiply the area of the room by the cost to carpet per foot.
So, the total cost is 2,857,680 dollars.
Problem 3
Find the area of a circle whose radius is 756 meters.
The area of the circle = 1,794,249.36 m²
Explanation
The area of a circle = πr²
Here, r = 756
Therefore, the area of the circle = π × 756² = 3.14 × 756 × 756 = 1,794,249.36 m².
Problem 4
The area of the square is 571,536 cm². Find the perimeter of the square.
The perimeter of the square is 3,024 cm.
Explanation
The area of the square = a²
Here, the area is 571,536 cm²
The length of the side is √571,536 = 756
Perimeter of the square = 4a
Here, a = 756
Therefore, the perimeter = 4 × 756 = 3,024.
Problem 5
Find the square of 757.
The square of 757 is 573,049.
Explanation
The square of 757 is multiplying 757 by 757.
So, the square = 757 × 757 = 573,049.
