Sage Kane · Answer 1

L = 20 W = 1

L = 10 W = 2

L = 5 W = 4

Study this carefully. It's a good problem to know how to do. The ancients solved problems by using this method. They started with biggest number they could on the left and multiply each number on the right as they went down (in this case by 2).
