x be the length
x-12 be the breadth
108=2(x)+2(x-12)
=2x+2x-24
108+24=4x
4x=132
x=132/4
=33

108=2(12+x+x)
108=2(12+2x)
108=24+4x
84=4x
21=x
So, 21 by 33 rectangle (the side that=33 was found by adding 21+12)

108=2(12+x+x)
54=12+2x
x=21
l=21
w=21+12=33

2*(w+l)=108
2*(x+(x+12))=108
2*(2x+24)=108
4x=108-24
4x=84
x=21
l=x+12
l=33
