Problem 2

Sarah is planning to tile her square garden of length 345 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full garden?

Okay, lets begin

The length of the garden = 345 feet The cost to tile 1 square foot of the garden = 5 dollars. To find the total cost to tile, we find the area of the garden, Area of the garden = area of the square = a² Here a = 345 Therefore, the area of the garden = 345² = 345 × 345 = 119025. The cost to tile the garden = 119025 × 5 = 595125. The total cost = 595125 dollars

Explanation

To find the cost to tile the garden, we multiply the area of the garden by the cost to tile per foot. So, the total cost is 595125 dollars.
