Answer:
108 divide 12 and i got 9
then i did 9-3 and i got 6.
12+12+9+9=42
So the perimeter is 42
Welp i don't know if it is correct or not
Step-by-step explanation:
42 inches
x=6
108/12=9
9-3=6
the length of the picture is 12 and the width is 9
12+12+9+9==42
39
difference=28
other number=11
so:
11+28=39
39 is your other number
4.60<9
