D Hope this helps it’s the only one that would make sense
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.
Answer:
80
Step-by-step explanation:
Plug it in.
So 5 x 2 (4 x 3- 2 x 2)
5x2(12-2x2)
5x2(12-4)
5x2(8)
(10)(8)
So, the answer is 80.
