Problema Solution
a rectangular room is three times as long as it is wide ans its perimeter is 48 meters find the length of the room
Answer provided by our tutors
let
l = the length of the rectangular room, l>0
w = the width of the rectangular room, w>0
a rectangular room is three times as long as it is wide:
l = 3w
its perimeter is 48 meters:
2(l + w) = 48
by solving the system of equations:
l = 3w
2(l + w) = 48
we find:
l = 18 m
w = 6 m

the length of the room is 18 meters.
