Problem 2

Jane wants to carpet a square room of length 663 feet. The cost to carpet a square foot is 5 dollars. How much will it cost to carpet the full room?

Okay, lets begin

The length of the room = 663 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 = 663

Therefore, the area of the room = 663² = 663 × 663 = 439,569.

The cost to carpet the room = 439,569 × 5 = 2,197,845.

The total cost = 2,197,845 dollars

Explanation
