Area of a triangle is equal to 1/2 b(h) so since you already have the height and base, all you need to do is input it back into the equation:

(10)(13)
Multiply 10 & 13 to equal

(130)
Then take half of 130 to get
A = 65
Answer:
You just do.
Step-by-step explanation:
That's all there is
X,=-(5±✓25-36) ,/ 2
x={-5±✓-11)/2
x= -5/2 ± i✓11/2
