Area of the square is 9x%5E4-24x%5E2%2B16+=+%283x%5E2+-+4%29%5E2 ==> a side has length 3x%5E2+-+4 ==> the perimeter is 4%283x%5E2+-+4%29+=+12x%5E2+-+16

Area of the square is 9x%5E4-24x%5E2%2B16
= %283x%5E2+-+4%29%5E2 ....=> a side has length 3x%5E2+-+4
...=> the perimeter is 4%2Aside...=>
4%283x%5E2+-+4%29+=+12x%5E2+-+16
