width $= 24$ $=24$
length $= 36$ $=36$

Explanation:

$P = 120$ $P=120$
$l = w + 12$ $l=w+12$
$P = 2 \cdot l + 2 \cdot w$ $P=2*l+2*w$
$120 = 2 (w + 12) + 2 \cdot w$ $120=2(w+12)+2*w$
$120 = 2 \cdot w + 24 + 2 \cdot w$ $120=2*w+24+2*w$
$120 = 4 \cdot w$ $120=4*w$
$96 = 4 \cdot w$ $96=4*w$
$24 = w$ $24=w$
$24 + 12 = l$ $24+12=l$
$36 = l$ $36=l$
