Problem 2

Sara is planning to carpet her square room of length 99880 feet. The cost to carpet a square foot is 3 dollars. Then how much will it cost to carpet the full room?

Okay, lets begin

The length of the room = 99880 feet The cost to carpet 1 square foot of room = 3 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 = 99880 Therefore, the area of the room = 99880² = 99880 × 99880 = 9976014400. The cost to carpet the room = 9976014400 × 3 = 29928043200. The total cost = 29928043200 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 29928043200 dollars.
