Answer:
1) 
2) 
Step-by-step explanation:
Assuming that our function is 
for the first case and 
for the second case.
Part 1
We can rewrite the expression like this:
And we can reorder the terms like this:
Now if we apply integral in both sides we got:
And after do the integrals we got:
Now we can use the initial condition 
And the final solution would be:
Part 2

Answer:
Step-by-step explanation:
Area of the shaded region = area of the large rectangular - area of the small rectangle
Area of rectangle is given as l*w
Area of the large rectangle = 
Expand
Area of large rectangle 
Area of small rectangle = 
Area of small rectangle = 
Area of shaded region =

You need to separate the different figures then add oall of the different areas together
21x squared, just add the numbers together
