For example, the square of 25 is 625, and the square root of 625 is ±25.
Solved Examples on Square of 225
Problem 1
Find the length of the square, where the area of the square is 50625 cm².
The area of a square = a² So, the area of a square = 50625 cm² So, the length = √50625 = 225. The length of each side = 225 cm
Explanation
The length of a square is 225 cm.
Because the area is 50625 cm², the length is √50625 = 225.
Problem 2
Lisa is planning to paint her square ceiling of length 225 feet. The cost to paint a foot is 3 dollars. Then how much will it cost to paint the full ceiling?
The length of the ceiling = 225 feet The cost to paint 1 square foot of ceiling = 3 dollars. To find the total cost to paint, we find the area of the ceiling, Area of the ceiling = area of the square = a² Here a = 225 Therefore, the area of the ceiling = 225² = 225 × 225 = 50625. The cost to paint the ceiling = 50625 × 3 = 151875. The total cost = 151875 dollars
Explanation
To find the cost to paint the ceiling, we multiply the area of the ceiling by the cost to paint per foot.
So, the total cost is 151875 dollars.
Problem 3
Find the area of a circle whose radius is 225 meters.
The area of the circle = 159043.5 m²
Explanation
The area of a circle = πr²
Here, r = 225
Therefore, the area of the circle = π × 225² = 3.14 × 225 × 225 = 159043.5 m².
Problem 4
The area of the square is 225 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 225 cm²
The length of the side is √225 = 15
Perimeter of the square = 4a
Here, a = 15
Therefore, the perimeter = 4 × 15 = 60.
Problem 5
Find the square of 226.
The square of 226 is 51076
Explanation
The square of 226 is multiplying 226 by 226.
So, the square = 226 × 226 = 51076
