To find the length of the rectangle, we can use the formula for the perimeter of a rectangle, which is P = 2L + 2W, where P is the perimeter, L is the length, and W is the width.
Given that the perimeter is 42 inches and the width is 6 inches, we can substitute these values into the formula and solve for L:
42 = 2L + 2(6)
42 = 2L + 12
30 = 2L
15 = L
Therefore, the length of the rectangle is 15 inches.
The correct response is:
15 inches
