Problem 2

Sarah is planning to tile her square patio of length 538 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full patio?

Okay, lets begin

The length of the patio = 538 feet

The cost to tile 1 square foot of patio = 5 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 = 538

Therefore, the area of the patio = 538² = 538 × 538 = 289,444.

The cost to tile the patio = 289,444 × 5 = 1,447,220.

The total cost = 1,447,220 dollars

Explanation

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

So, the total cost is 1,447,220 dollars.
