Let the two sides be x and x + 3
Area = 54 cm^2
1/2 (x)(x+3) = 54

x² + 3x = 108

x² + 3x - 108 = 0

(x+12)(x-9) = 0

x = 9

Sides are 9 cm and 12 cm

Hypotenuse =  \sqrt{9^2 + 12^2}
                
                    =  \sqrt{81 + 144}

                    =  \sqrt{225}
  
                   = 15 cm

Perimeter of triangle = 9 + 12 + 15 = 36  cm
