Answer:
36
Explanation:
We must determine the x and y intercepts of the parabola:
When y=0, x=0 or x=10
WE know that the point of the triangle base is x and x+8. We can substitute this into the parabola equation because the endpoints are on the parabola.
f(x+8)

f(x+8)

f(x)=f(x+8)

solve for x


Therefore the heigh is f(1):

The area of the triangle is 1/2 base x height:
