Answer:
a = 33.4
Step-by-step explanation:
The short sides are both 1.2. You have to take them into account.
P = 2L + 2W
L is arbitrarily chosen to be the long side. The short side is W.
Givens
P = 69.2
L = a
W = 1.2
Solution
69.2 = 2 * 1.2 + 2a
69.2 = 2.4 + 2a
69.2 - 2.4 = 2a
66.8 = 2a
66.8/2 = a
a = 33.4
