Problema Solution

Answer provided by our tutors
let
w = the width of the room, w>0
l = the length of the room, l>0
room is 1.5 times long as it is wide
l = 1.5*w
the perimeter is 25
2*(w + l) = 25
by solving the system of equations
l = 1.5*w
2*(w + l) = 25
we find
w = 7.5
l = 5
the dimensions of the room are 7.5 and 5.
