Does anybody know how to find area of a triangle?

Explanation:
➡ Pythagorean Theorem: a² + b² = c²
➡ We eliminate D - So the Pythagorean theorem is used for right triangles and that equation is a² + b² = c² and answer D doesn't have anything squared.
➡ Hypotenuse is what letter in the theorem? It is Letter C!
➡ 11² + 60² = 3721
Hope this helps! :)
