    2 a + 2 b = 372
    5 b^2 = a b

    If one side is a then total length is 4a and one breadth is a

    so total perimeter is 4a+4a+2a=372
    10a=372
    a=37.2
    so area of one square is 37.2*37.2=1383.84

    If one side is a, then the total length is 5a...

    One side is 5a, not 4a; so 12a = 372 ; a = 31 ; a*a = 961 (as per Sir Jasper)

    You'll get nobody clicking on your commercial link if you keep making these silly mistakes!!
