Answer:

L=W+12

2L+2W=48

2(W+12)+2W=48

2W+24+2W=48

4W=48-24

4W=24

W=24/4

W=6 ANS. FOR THE WIDTH.

L=6+12=18 ANS. FOR THE LENGTH.

PROOF:

2*18+2*6=48

36+12=48

48=48

Answer:

6 cm by 18 cm

Step-by-step explanation:

use x and x+12

2(x) + 2(x+12)=48

2x +2x+24=48

4x+24=48

4x=24

x=6 and (6+12)=18
