Problema Solution
The length of the garden is 5 m longer than its width and the area is 14 m2. how long is the garden?
Answer provided by our tutors
let
l = the length of the garden, l>0
w = the width of the garden, w>0
A = 14 m^2 the area of the garden
The length of the garden is 5 m longer than its width
l = 5 + w
The formula for area A = length*width:
l*w = 14
plug l = 5 + w into l*w = 14
(5 + w)*w = 14
by solving we find
w = 2 m

l = w + 5
l = 2 + 5
l = 7 m
the garden is 7 meters long.
