Problem 2

Sarah is planning to tile her square backyard, which measures 919 feet on each side. The cost to tile a square foot is 5 dollars. How much will it cost to tile the entire backyard?

Okay, lets begin

The length of the backyard = 919 feet The cost to tile 1 square foot = 5 dollars. To find the total cost to tile, we find the area of the backyard: Area of the backyard = area of the square = a² Here a = 919 Therefore, the area of the backyard = 919² = 919 × 919 = 844561. The cost to tile the backyard = 844561 × 5 = 4222805. The total cost = 4222805 dollars

Explanation

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

So, the total cost is 4222805 dollars.
