Solved Examples on Square of 798
Problem 1
Find the length of a square, where the area of the square is 636804 cm².
The area of a square = a² So, the area of a square = 636804 cm² So, the length = √636804 = 798. The length of each side = 798 cm
Explanation
The length of a square is 798 cm.
Because the area is 636804 cm², the length is √636804 = 798.
Problem 2
Lisa is planning to tile her square kitchen floor of length 798 feet. The cost to tile a foot is 12 dollars. Then how much will it cost to tile the full floor?
The length of the floor = 798 feet The cost to tile 1 square foot of floor = 12 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 = 798 Therefore, the area of the floor = 798² = 798 × 798 = 636804. The cost to tile the floor = 636804 × 12 = 7641648. The total cost = 7641648 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 7641648 dollars.
Problem 3
Find the area of a circle whose radius is 798 meters.
The area of the circle = 2000604.72 m²
Explanation
The area of a circle = πr²
Here, r = 798
Therefore, the area of the circle = π × 798² = 3.14 × 798 × 798 = 2000604.72 m².
Problem 4
The area of the square is 636804 cm². Find the perimeter of the square.
The perimeter of the square is 3192 cm
Explanation
The area of the square = a²
Here, the area is 636804 cm²
The length of the side is √636804 = 798
Perimeter of the square = 4a
Here, a = 798
Therefore, the perimeter = 4 × 798 = 3192.
Problem 5
Find the square of 799.
The square of 799 is 638401
Explanation
The square of 799 is multiplying 799 by 799.
So, the square = 799 × 799 = 638401
