Hi

second side is 4 less than twice the first side. the third side is 10 less than twice the second side: 2(2x-4)-10 = 4x-18

Let x, (2x-4) and (4x-18) represent the respective sides

Question states***perimeter of a triangle is 48 cm

x + (2x-4)+(4x-18)= 48cm

   7x = 70

    x = 10cm, 1st side, 2nd side is 16cm and the 3rd side is  22cm

 10cm +16cm +22cm = 48cm
