and rewrite it as
but 5 less than 3 × the width is 3 × the width  5 so the expression can be written
Finally if I let the width be W cm and the length be L cm then I have
You are also told that the perimeter is 54 cm. The perimeter is the distance all the way around the rectangle so
Substitute L = 3W  5 into this expression and solve for W. Penny
