Problem 1

Find the length of the square, where the area of the square is 50625 cm².

Okay, lets begin

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?

Okay, lets begin

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.
