a rectangular garden has a perimeter of 140m.its width is three quarter of its length.
what is the length and width?

If you really want the help of an expert in this subject, you'll follow directions and put the SUBJECT in the School Subject box.

if the length is x, the width is 3/4 x
2(x + 3/4 x) = 140
7/4 x = 70
x = 40
so the garden is 30 x 40
