Problem 1

Find the length of the square, where the area of the square is 60,025 cm².

Okay, lets begin

The area of a square = a² So, the area of a square = 60,025 cm² So, the length = √60,025 = 245. The length of each side = 245 cm

Explanation

The length of a square is 245 cm.

Because the area is 60,025 cm² the length is √60,025 = 245.

Problem 2

Alice is planning to tile her square garden of length 245 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full garden?

Okay, lets begin

The length of the garden = 245 feet The cost to tile 1 square foot of the garden = 5 dollars. To find the total cost to tile, we find the area of the garden, Area of the garden = area of the square = a² Here a = 245 Therefore, the area of the garden = 245² = 245 × 245 = 60,025. The cost to tile the garden = 60,025 × 5 = 300,125. The total cost = 300,125 dollars

Explanation

To find the cost to tile the garden, we multiply the area of the garden by the cost to tile per foot.

So, the total cost is 300,125 dollars.
