I solved it and I got 30 for the Length but the answer in the book is 24. This is how I solved: A=LW so 240=(4L)(2W) I then divided both sides by 2 to eliminate the W and solve for L. So then I got 120=4L then I divided both sides by 4 to solve for L and I get L=30. Apparently thats not the answer. 24 is. Please help if you can solve this problem. Thank You soo Much!
