Answer:
Length = 28 inches
Width = 8 inches
Step-by-step explanation:
Let length be L
Let Width be W
Given : W = 1 + (1/4)L
Perimeter = 2 x ( L + W)
[tex]72 = 2 (L + (1 + \frac{1}{4} L))\\\\36 = L + 1 + \frac{1}{4} L\\\\36 - 1 = \frac{5}{4} L\\\\35 = \frac{5}{4} L\\\\5L = 35 \times 4\\\\L = \frac{140}{5} = 28 \ in[/tex]
[tex]W = 1 + (\frac{1}{4} \times 28) = 1 + 7 = 8 \ in[/tex]
