Solved Examples on Square of 807
Problem 1
Find the length of the square, where the area of the square is 651,249 cm².
The area of a square = a² So, the area of a square = 651,249 cm² So, the length = √651,249 = 807. The length of each side = 807 cm
Explanation
The length of a square is 807 cm.
Because the area is 651,249 cm², the length is √651,249 = 807.
Problem 2
Sarah is planning to carpet her square room of length 807 feet. The cost to carpet a foot is 5 dollars. How much will it cost to carpet the full room?
The length of the room = 807 feet The cost to carpet 1 square foot of the room = 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 = 807 Therefore, the area of the room = 807² = 807 × 807 = 651,249. The cost to carpet the room = 651,249 × 5 = 3,256,245. The total cost = 3,256,245 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 3,256,245 dollars.
Problem 3
Find the area of a circle whose radius is 807 meters.
The area of the circle = 2,046,389.86 m²
Explanation
The area of a circle = πr²
Here, r = 807
Therefore, the area of the circle = π × 807² = 3.14 × 807 × 807 = 2,046,389.86 m².
Problem 4
The area of the square is 651,249 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 651,249 cm²
The length of the side is √651,249 = 807
Perimeter of the square = 4a
Here, a = 807
Therefore, the perimeter = 4 × 807 = 3,228.
Problem 5
Find the square of 808.
The square of 808 is 652,864
Explanation
The square of 808 is multiplying 808 by 808.
So, the square = 808 × 808 = 652,864
