Answer:
18
Step-by-step explanation:
The length of side AC can be found by counting the squares between AC: 8.
The length of side BC can be found using the Pythagorean Theorem. B is 3 units to the right of C and 4 units above C. Thus:
|BC| = √(3² + 4²) = √25 = 5.
|AC| has the same length: 5.
Thus, the perimeter of this triangle is 5 + 5 + 8, or 18.
