Problem 2

Alex wants to tile his square courtyard of length 877 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full courtyard?

Okay, lets begin

The length of the courtyard = 877 feet

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

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

Area of the courtyard = area of the square = a²

Here a = 877

Therefore, the area of the courtyard = 877² = 877 × 877 = 769129.

The cost to tile the courtyard = 769129 × 5 = 3845645.

The total cost = 3845645 dollars

Explanation

To find the cost to tile the courtyard, we multiply the area of the courtyard by the cost to tile per foot. So, the total cost is 3845645 dollars.
