Base on your question where as ABC has the value of the 30 unit, 40 unit and 60 units length and the XYZ is R times the long as the sides of ABC so the ask is to find its expression. So first is you must get the perimeter of the ABC triangle which is 130units, then get the perimeter of XYZ and the expression would be 130R
