To find the length, we need to subtract the width from the perimeter of the rectangle.
The perimeter of a rectangle is given by the formula: perimeter = 2(length + width)
In this case, the perimeter is 40 feet, and the width is 8 feet.
40 = 2(length + 8)
Divide both sides of the equation by 2:
20 = length + 8
Subtract 8 from both sides of the equation:
12 = length
Therefore, the length will be 12 feet.
