Answer:
how many students are in the class
Step-by-step explanation:
Answer:
42 feet
Step-by-step explanation:
1) remeber how 1 foot=12 inches
we need to find "x" feet for 144 inches
so

2) cross multiply
144=12x
divide both sides by 12
12=x
so 144 inches is 12 feet, we need to do the exact same thing for the width

108=12x
9=x
the length is 12 feet and width is 9 feet
to find perimeter:
2(l)+2(w)
2*12+2*9
24+18=42
Hope this helps!
