The perimeter of a square window is 17ft 4inches. Find the area in square feet and in inches.?

Question

I have answers for this problem but the computer keeps telling me that area for one of them is wrong but won't tell me which one. Help me out so I can compare my answers to see where I went wrong.

Answer 1

if it is a square all sides have the same length; if the total perimeter is 17'4", there are a total of 17x12+4=208 inches, or 52 inches on a side

the total area is then 52^2 sq inches = 2704 sq inches

1 sq ft = 12inx12 in = 144 sq inches

so the total area =2704 sq in = 2704 sq in/144 sq in/sq ft = 18.78 sq ft
