Problem 2

Emily is planning to paint her square wall of length 545 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 = 545 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 = 545

Therefore, the area of the wall = 545² = 545 × 545 = 297025.

The cost to paint the wall = 297025 × 5 = 1485125.

The total cost = 1485125 dollars

Explanation

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

So, the total cost is 1485125 dollars.
