Answer 2

A^2 + B^2 = C^2 is the formula you will use
you know that C= 24ft, and that a and b must be the same number (because it is a square ceiling)
24^2 = A^2 + B^2
576 = A^2 + B^2
and since a and b must be the same, A^2 must equal half of 576 and B^2 must equal half of 576
so A^2 = 288 and B^2 = 288
which means that a= 16.97 and b=16.97
perimeter is 67.88 ft

hope this helps!
