Problem 2

John is planning to tile his square garden of length 8281 feet. The cost to tile a square foot is 2 dollars. Then how much will it cost to tile the full garden?

Okay, lets begin

The length of the garden = 8281 feet The cost to tile 1 square foot of garden = 2 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 = 8281 Therefore, the area of the garden = 8281² = 8281 × 8281 = 68,556,761. The cost to tile the garden = 68,556,761 × 2 = 137,113,522. The total cost = 137,113,522 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 137,113,522 dollars.
