Problem 2

Lisa is planning to tile her square kitchen floor of length 798 feet. The cost to tile a foot is 12 dollars. Then how much will it cost to tile the full floor?

Okay, lets begin

The length of the floor = 798 feet The cost to tile 1 square foot of floor = 12 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 = 798 Therefore, the area of the floor = 798² = 798 × 798 = 636804. The cost to tile the floor = 636804 × 12 = 7641648. The total cost = 7641648 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 7641648 dollars.
