Problem 2

Anna is planning to carpet her square room of length 211 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 = 211 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 = 211 Therefore, the area of the room = 211² = 211 × 211 = 44521. The cost to carpet the room = 44521 × 5 = 222605. The total cost = 222605 dollars

Explanation

To find the cost to carpet the room, we multiply the area of the room by cost to carpet per foot.

So, the total cost is 222605 dollars.
