when the sides are the same legnth, that is max area
(I can find the max area with calculus but I don't think you know that)
so
if we assume that they are equal
L=W
376=perimiter
P=2(L+W)
376=2(L+W)
376=2(L+L)
376=2(2L)
376=4L
divide both sides by 4
94=L
the dimeintions are 94 by 94, if we mulipy we get 8836ft
C is answer
(note: for those people who say rectangles have to have different side legnths, that is incorrect because the requirement is 4 right angles, all squares are recangles, but not all rectangles are squares)
