27
<p>Okay, lets begin</p>
27
<p>Okay, lets begin</p>
28
<p>The length of the wall = 728 feet The cost to paint 1 square foot of wall = 3 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 = 728 Therefore, the area of the wall = 728² = 728 × 728 = 529,984. The cost to paint the wall = 529,984 × 3 = 1,589,952. The total cost = 1,589,952 dollars</p>
