Problema Solution
The length of a rectangle is
7 m
more than double the width, and the area of the rectangle is
99 m2
. Find the dimensions of the rectangle.
Answer provided by our tutors
Let
l = the length of the rectangle, l>0
w = the width of the rectangle, w>0
A = 99 m^2 the are of the rectangle
The length of a rectangle is 7 m more than double the width:
l = 7 + 2w
The area of the rectangle is 99 m^2:
l*w = 99
Plug l = t + 2w into the last equation:
(7 + 2w)*w = 99

w = 5.5 m
l = 7 + 2*5.5
l = 18 m
The dimensions of the rectangle are: the length is 18 meters and the width is 5.5 meters.
