Answer:
answer is c makes sense because you just add 1.25 x 20
15 - 9 = 6 6÷3=2 X=2
You do the inverse operation
The perimeter represents the amount of wood needed and the area represents the amount of class needed.
so 2*(2/3) + 2(2) = 4/3 + 4= 4 4/3 or 5 1/3 wood is needed for the border.
for the mirror, you will need the area= 4/3 * 2 = 8/3 sq yds or 2 2/3 sq yards is needed.
14.29 * .0725 = 1.04
1.04 * 3 = 3.12
