Answer:

13.5

Step-by-step explanation:

A triangles area is base x height divided by two.

Height is 3, and base is 9.

9 x 3 = 27 / 2 = 13.5

The area of a triangle is
a = base x height / 2

but only for a right triangle meaning one of the angles of the triangle has to be 90 degrees. So we split the triangle in half and then solve for the area of the two triangles and add them together.

area of triangle 1 = 3 x 6 / 2 or 9
area of triangle 2 = 3 x 3 / 2 or 4.5

Total area is 13.5

I hope this is this helps and is the BRAINLIEST!!

Good Luck with your studies!
