Problem 2

Lisa wants to carpet her square room with a side length of 542 inches. The cost to carpet a square inch is 2 dollars. How much will it cost to carpet the full room?

Okay, lets begin

The length of the room = 542 inches

The cost to carpet 1 square inch of the room = 2 dollars.

To find the total cost to carpet, we find the area of the room,

Area of the room = area of the square = a²
