Let length be l, and w for width.

2L + 2W= perimeter or = 70

2W= 70 - 2L

W= 35 - L

Now, one knows the L/W ratio, so

L/W=4/5 and manipulating that

L= 4W/5

{Putting that in the above equation)

W= 35 - L = 35 - 4W/5

adding 4W/5 to both sides..

W+ 4W/5 =35

9W/5= 35

9W=35*5

W= 35*5/9= 19.4 feet

but L+ W= 35, so L= 35-19.4 feet

Check: Is L/W= 4/5 ?

15.6/18.4= .8, so it checks

Thank you so much!
