Answer:
274.05 (I assume they round it to A. 274.1)
Step-by-step explanation:
The figure seems to be comprised of 7 triangles, each of base 8.7 and height 9.
total area would be
7 * (8.7 * 9 / 2) = 7 * 39.15 = 274.05
F(x) = x^2 + 5x
F(5) = 5^2 + 5(5)
F(5) = 25 + 25
F(5) = 50
G(x) = 2x + 1
G(6) = 2(6) + 1
G(6) = 12 + 1
G(6) = 13
F(5) + G(6) = 50 + 13 = 63 <==
