cm2

area = 44 cm²

Step-by-step explanation:

rectangle area = bh = 8 x 4 = 32 cm²

triangle height² = 5² - 4³ = 25 - 16 = 9

triangle height = 3

triangle area = 1/2bh = 1/2(8)(3) = 12 cm²

32 cm² + 12 cm² = 44 cm²

area = 44 cm²

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
