Answer:
12 units
Step-by-step explanation:
Both triangles have the same perimeter, so we can figure out 1 and have the answer for both.
The legs of triangle AABC are 3 and 4, so we can use the Pythagorean Theorem to figure out the other side.
3² + 4² =
9 + 16 = 25
√25 = 5
To find the perimeter, just add the three sides.
3 + 4 + 5 = 12 units
