What is the perimeter of the triangle

Answer:
it's 65 because if u count the inside of the boxes u get 65
Answer:
34
Step-by-step explanation:
to get the perimeter you add the side-A with Base-B and Side-C.
The base at the bottom is 10 and the two symmetrical sides is 12.
P= a + b + c
34= 12 + 10 + 12
