Problema Solution
the perimeter of a rectangular garden is 4.8 meters. Its length is twice its width. How wide is the garden?
Answer provided by our tutors
let
l = the length of the garden
w = the width of the garden
the perimeter of a rectangular garden is 4.8 meters
2(l + w) = 4.8
length is twice its width
l = 2w
plug l = 2w into 2(l + w) = 4.8 we get
2(2w + w) = 48
by solving we find
w = 8 m
