Problem 2

Sarah is planning to carpet her square room of length 765 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 = 765 feet

The cost to carpet 1 square foot of the 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 = 765

Therefore, the area of the room = 765² = 765 × 765 = 585,225.

The cost to carpet the room = 585,225 × 5 = 2,926,125.

The total cost = 2,926,125 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 2,926,125 dollars.
