The length of a rectangle is 3 centimeters less than twice its width. The perimeter of he rectangles is 48 cm. What is the dimensions of the rectangle?

Question

Let the length of the rectangle be l and width be w
Since it is given that the length is 3cm less than twice the width we have
l=2w-3
But
Perimeter P=2(w+l)
48=2(w+l)
Dividing both sides by 2 we get
24=l+w
28=2w-3+w
solving this we will get the value of w.
Substituting in 
l=2w-3 we can find l

Does this help :)
