I am not completely sure if tis is correct. I just took 16 and multiply them for the answer B and C. hope this can help you.
Answer:
75cm^2
Step-by-step explanation:
The formula for the area of a parallelogram is the same as a rectangle. lw=A
15. 6x + 12
16. 12y - 4
17. - 15p - 21
18. 24 - 8x
19. 7 - 42c
20. -20 + 15y
21. 3(x + 4)
22. 5(3 - 2k)
23. 3(3a + 5)
24. - 2(10 + 3b)
25. B) 4(2n - 5)
26. D) 8(3 - 2r)
