Total=80

One triangle=40

Step-by-step explanation:

The Width is given, it is 10. So if the triangle is cut in half, the length of the black dotted lines would be 10/2 which is 5.

It is also given that the height is 16. So to find the area, you have to do (16 x 5)/2 which would be 40. So the area of one triangle is 40 and it is the same for the other, so the total is 40 + 40 = 80.

Hope this helps!
