Problem 2

Sarah wants to lay tiles on her square courtyard of length 1128 feet. The cost to lay a tile per square foot is 5 dollars. How much will it cost to tile the entire courtyard?

Okay, lets begin

The length of the courtyard = 1128 feet The cost to lay 1 square foot of tile = 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 = 1128 Therefore, the area of the courtyard = 1128² = 1128 × 1128 = 1,272,384. The cost to tile the courtyard = 1,272,384 × 5 = 6,361,920. The total cost = 6,361,920 dollars

Explanation

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