Question

l+w+c=216
w+l=3*c
c+l=w/2
c=?
w=?
l=?

Answer 1

Because w+l=3*c
So l+w+c=216
3*c+c=216
4c=216
c=216/4
c=54 .
c+l=w/2
So w/2+w=216
3w/2=216
w=(216×2)÷3
w=144

Now;l+144+54=216
l=216-198
l=18
Therefore; l=18;c=54 and w=144

Answer 2

l+w+c=216
l+w=3*c
So,3*c+c=216
4*c=216
c=216/4=54

l+w=3*c
w=3*c-l
c+l=w/2
w=2(c+l)
So,3*c-l=2c+2l
3c-2c=2l+l
c=3l
54/3=l=18

c+l=w/2
w/2=54+18
w=72*2=144


c=54
l=18
&w=144
