In a rectanglew there are two equal lengths and two equal widths.
P = L + L + W + W,
where P = perimeter,
L = Length,
W = width, so
P = 2L + 2W
You are given P = 48 in. and W = 9 in., so substitute these values into the perimeter equation and solve for L:
P = 2L + 2W
48 = 2L + 2(9)
48 = 2L + 18
30 = 2L
2L = 30
L = 15
