Problema Solution
The area of a garden is 160 square meters. suppose the length of the garden is 3 more than twice its width. what is the length of the garden?
Answer provided by our tutors
let
l = the length of the garden, l>0
w = the width of the garden, w>0
the length of the garden is 3 more than twice its width
l = 3 + 2w
the area of a garden is 160 square meters
l*w = 160
plug l = 3 + 2w into l*w = 160
(3 + 2w)w = 160
by solving we find
w = 8.23 m
click here to see the step by step solution of the equation
l = 3 + 2*8.23
l = 19.46 m
the length of the garden is 19.46 m.
