Problem 2

Sarah wants to carpet her square living room, which has a side length of 145 feet. The cost to carpet a square foot is 5 dollars. How much will it cost to carpet the entire room?

Okay, lets begin

The side length of the room = 145 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 = 145 Therefore, the area of the room = 145² = 145 × 145 = 21,025. The cost to carpet the room = 21,025 × 5 = 105,125. The total cost = 105,125 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 105,125 dollars.
