The volume of a prism is the product obtained when multiplying the area of its base to its height. If the two given solid figures have the same volume and the same height then, the areas of their bases are also equal. Thus, the answer is letter D.
F(x) = 3x + 5/2
f(a+2) = 3(a+2) + 5/2 = 3a+6 + 5/2
= 3a + (12+5)/2 = 3a + 17/2
