Problem 2

Lisa is planning to paint her square wall of length 609 feet. The cost to paint a foot is 5 dollars. Then how much will it cost to paint the full wall?

Okay, lets begin

The length of the wall = 609 feet The cost to paint 1 square foot of wall = 5 dollars. To find the total cost to paint, we find the area of the wall, Area of the wall = area of the square = a² Here a = 609 Therefore, the area of the wall = 609² = 609 × 609 = 370,881. The cost to paint the wall = 370,881 × 5 = 1,854,405. The total cost = 1,854,405 dollars

Explanation

To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot.

So, the total cost is 1,854,405 dollars.
