5 1/2 ft equals 66 inches
Answer:
933.3333333
Step-by-step explanation:
s = 2(lw + lh + wh)
Divide each side by 2 : s/2 = lw + lh + wh
Subtract 'lh' from each side: s/2 - lh = lw + wh
Combine the 'w' terms: s/2 - lh = w(l + h)
Divide each side by (l + h): (s/2 - lh) / (l + h) = w
1/3
because a foot is a third of a yard and a yard is 3 feet.
