Problem 2

Sarah is planning to tile her square floor of length 388 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full floor?

Okay, lets begin

The length of the floor = 388 feet

The cost to tile 1 square foot of floor = 5 dollars.

To find the total cost to tile, we find the area of the floor,

Area of the floor = area of the square = a²

Here a = 388 Therefore, the area of the floor = 388² = 388 × 388 = 150544.

The cost to tile the floor = 150544 × 5 = 752720.

The total cost = 752720 dollars

Explanation

To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot.

So, the total cost is 752720 dollars.
