Answer:
68
Step-by-step explanation:
The formula of a trapezoid is [tex]A = \frac{a+b}{2} h[/tex]
Use the values given in the equation:
[tex]A = \frac{17+9}{2} *8[/tex]
A = 13*8
A=104 (This the area of the overal trapezoid)
To find the area of the inner unshaded triangle, simply multiply 9 (Base) times height (8) * 1/2 to get 36
Then subtract 36 from 104 and you get 68
