Answer:
8. True
9. 105 yd²
Step-by-step explanation:
#8:
We are trying to text if the missing length of the trapezoid on this question is 9. We know the base is 16, and the gap is 7. Subtract 16 from 7 to get 9. Since we got 9, this statement is true.
#9:
I'll split this into a 10*8 rectangle and a triangle with a base of 10 and a height of 5.
(10 * 8) + 1/2(10 * 5)
First, multiply 10 by 8 to get 80.
80 + 1/2(10 * 5)
Then, multiply 10 by 5 to get 50.
80 + 1/2(50)
Now multiply 1/2 by 50 get 25.
80 + 25
Lastly, add 25 to 80 to get 105.
The area of this figure is 105 yd².
