Problem 1

Find the length of the square, where the area of the square is 18225 cm².

Okay, lets begin

The area of a square = a² So, the area of a square = 18225 cm² So, the length = √18225 = 135. The length of each side = 135 cm

Explanation

The length of a square is 135 cm.

Because the area is 18225 cm², the length is √18225 = 135.

Problem 2

Sarah is planning to carpet her square room of length 135 feet. The cost to carpet a foot is 5 dollars. Then how much will it cost to carpet the full room?

Okay, lets begin

The length of the room = 135 feet The cost to carpet 1 square foot of 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 = 135 Therefore, the area of the room = 135² = 135 × 135 = 18225. The cost to carpet the room = 18225 × 5 = 91125. The total cost = 91125 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 91125 dollars.
