The answer to the question
Answer:
The answer is 367
Step-by-step explanation:
Lets w width, l length, y amount add, A area, P perimeter
A=lw=(3+y)(2)=6+2y ft²
p= 2l+2w= 2(3+y)+2(2)= 6+2y+4 =10+2y
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.
