Answer:
150Ft^2
Step-by-step explanation:
The area of a parallelogram is A=BH where B is base length and H is height. I'm not sure why there is information about a triangular base, maybe an illustration would help. But with the information provided, the base times  height is equal to 150 Ft^2. Check out the Kahn Academy video for a better explanation

Answer:
Kendra should have divided by 2 instead of multiplying by 2 
Step-by-step explanation:
40 percent = percentage who plan to attend
100% = total percentage of student
From the question ;
When reducing percentages, division is employed and this the equation should be :

20/50
= 0.4 
0.4 * 50 
= 20 students
