The answer is D .. one hundred random students from the sixth grade
Answer:
80 square units
536.6
Step-by-step explanation:
First one.
2 Trapezoids
A =
x h
A =
x 2
A = 16
One rectangle
A = b x h
A = 6 x 8
A = 48
Total Area = 16 + 16 + 48 = 80
Second one:
Two triangles:
A =
A = 
A =
A = 43.3
One large rectangle
A = b x h
A = 30 x 15
A = 450
Total Area = 450 + 43.3 + 43.3 = 536.6
