Answer 2

Step-by-step explanation:

IF WE LOOK CLOSELY WE CAN SEE IT'S A RIGHT TRIANGLE

{5}^{2} + {12}^{2} = {13}^{2}52+122=132

FORMULA OF AREA OF A TRIANGLE

\begin{gathered} \frac{1}{2} \times hight \times base \\ \frac{1}{2} \times 12 \times 5 \\ 6 \times 5 \\ 30\end{gathered}21×hight×base21×12×56×530
