Given: 60 inches of pipe. cut into to pieces. Formed into 2 squares with a total area of 117 sq inches.
Let the first piece be A. Then the second piece = (60-A)
To form a square with perimeter of A, each side must be A/4. So the area of that square is A%5E2%2F16
Likewise, the area of the other frame is %28%2860-A%29%2F4%29%5E2
or %283600+-120A+%2BA%5E2%29%2F16
The sum of the two areas is 117
So
117+=+%28A%5E2%2F16%29+%2B+%283600+-120A+%2BA%5E2%29%2F16
0+=+A%5E2+-60A+%2B+864 factor or use quadratic equation
+0+=+%28A+-24%29%28A+-+36%29
So A is 24 and the other piece is 36.
