Solved Examples on Square of 615
Problem 1
Find the length of the square, where the area of the square is 378225 cm².
The area of a square = a² So, the area of a square = 378225 cm² So, the length = √378225 = 615. The length of each side = 615 cm
Explanation
The length of a square is 615 cm.
Because the area is 378225 cm² the length is √378225 = 615.
Problem 2
Sara wants to tile her square floor of length 615 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full floor?
The length of the floor = 615 feet The cost to tile 1 square foot of floor = 5 dollars. To find the total cost to tile, we find the area of the floor, Area of the floor = area of the square = a² Here a = 615 Therefore, the area of the floor = 615² = 615 × 615 = 378225. The cost to tile the floor = 378225 × 5 = 1891125. The total cost = 1891125 dollars
Explanation
To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot.
So, the total cost is 1891125 dollars.
Problem 3
Find the area of a circle whose radius is 615 meters.
The area of the circle = 1,188,495.75 m²
Explanation
The area of a circle = πr²
Here, r = 615
Therefore, the area of the circle = π × 615² = 3.14 × 615 × 615 = 1,188,495.75 m².
Problem 4
The area of the square is 379456 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 379456 cm²
The length of the side is √379456 = 616
Perimeter of the square = 4a
Here, a = 616
Therefore, the perimeter = 4 × 616 = 2464.
Problem 5
Find the square of 616.
The square of 616 is 379456
Explanation
The square of 616 is multiplying 616 by 616.
So, the square = 616 × 616 = 379456
