Two sides of a rectangle differ by 3.5cm.Find the dimensions of the rectangle if its perimeter is 67cm.
the answer should contain step by step and understandable explanation.
One side = x The other side = x+3.5 Perimeter is 2(L*w) Perimeter is 2(x + x + 3.5) 2(2x + 3.5) = 67 4x + 7 = 67 4x = 60, x = 15 15 + 3.5 = 18.5 One side is 15cm, the other side is 18.5 cm
