You would divide the total area by the length.
8 3/4 divided by 3 1/2
35/4 / 7/2
35/4 * 2/7 = 70/28 =2 1/2 ft
I believe in Vertex form it would be (-5,-4)
Answer:A
Step-by-step explanation:
hmmm let's find the distance between B and C first off.

hmmm if BC is that much, then AB + AC = 7, since AB + AC + BC = 12 which is the perimeter, Check the picture below.
