Answer:
9
Step-by-step explanation:
We know that the perimeter is 30.
2 x 6 is 12 and 30 - 12 is 18. We subtract 12 because we want to know the other sides
18 is the length of the remaining sides so we just divide by 2 and we get 9.
when you divide 3/4 by 1/8 you get 6
79.8
7.98*10=
to check
(1/10)*79.8=
7.98
