Problem 2

Sarah wants to lay tiles on her square patio of length 386 feet. The cost to lay a tile per square foot is 3 dollars. Then how much will it cost to tile the full patio?

Okay, lets begin

The length of the patio = 386 feet The cost to lay 1 square foot of tile = 3 dollars. To find the total cost to tile, we find the area of the patio, Area of the patio = area of the square = a² Here a = 386 Therefore, the area of the patio = 386² = 386 × 386 = 148996. The cost to tile the patio = 148996 × 3 = 446988. The total cost = 446988 dollars

Explanation

To find the cost to tile the patio, we multiply the area of the patio by the cost to lay per square foot.

So, the total cost is 446988 dollars.
