l= 2w
w= w
Therefore, 2(2w+w)=720
4w + 2w = 6w
720/6 = 120
W = 120ft.
L = 240ft.

wite the system of equations which represents the situation where the perimeter of a lot is 720 feet. the length is twice the width.

With W being the width, and L being the length, one equation is: L = 2W

The other equation is: 2L + 2W = 720 ------- L + W = 360

The system of equations is therefore:

highlight_green%28L+=+2W%29

highlight_green%28L+%2B+W+=+360%29

You can then solve the system to determine the length and the width, if you so wish.
