Please help is the perimeter rational or irrational

To find the area you multiply l x w so, to find the sides you do the opposite, sq root of 24,200 (we can use the square root because we know it is a square and all sides are equal)=155.563492. This is only the length of one side. 155.563492*4=622.253968 which is a rational number.
