Hello!
To find the area of a triangle, you find half of the the product of the base and height. This can represented as 1/2(bh)=A. A and D multiply by 2, so they are incorrect. B adds 10 and 6, it does not multiply them, so it is not the answer either.
As you can see, C matches our formula, so it is our answer.
I hope this helps!
