A homeowner designs a rectangular garden such that the length is 20 feet more than twice the width. If 310 feet of picket fencing are to be used, find the length and width of the garden.

Math 
bobpursley,
L=2W+20
310=2L+2W
Put the expression for L from the first equation, into the second, and solve for W. Then go back and solve for L

Cole,
What do you mean?

Math 
bobpursley,
310=2(2W+20)+2W
solve for W first.
