Part 1:
Gnom [1K]
P = 2(L + W)
L = 4/3W

P = 2(4/3W + W) <=== part 1 is D

when P = 28
28 = 2(4/3W + W)
28/2 = 4/3W + 3/3W
14 = 7/3W
14 / (7/3) = W
14 * 3/7 = W
42/7 = W
6 = W....width is 6 inches

L = 4/3W
L = 4/3(6)
L = 24/3
L = 8....length is 8 inches

A = L * W
A = 8 * 6
A = 48 in^2 <==== part 2
