The perimeter of a rectangle is 40 inches. If the width of the rectangle is 8 inches, what is the length?
Let the length of the rectangle be L inches.
The perimeter of a rectangle is given by the formula: 2(length + width)
Given that the width is 8 inches and the perimeter is 40 inches, we can write the equation:
40 = 2(L + 8)
Simplify the equation:
40 = 2L + 16
Subtract 16 from both sides:
24 = 2L
Divide by 2:
L = 12
Therefore, the length of the rectangle is 12 inches.
