The height is 5 and 1/4 then the base is 2 and 1/2
You can convert these fractions into decimals and them multiply them to get your area.
True, volume is a tree dimensional measure.
The answer is: [A]: 45x² + 81x + 36 .

Explanation: Use "FOIL" technique: (First, Outer, Inner, and Last Terms);
then, combine the "like terms", to simplify.
__________________________________________
(5x+4)(9x+9) = 45x² + 45x + 36x + 35 = 45x² + 81x + 36 .
(which is answer choice: "A".).

156°
D is a 24° angle, and is placed in a 90° angle, so 90-24=66
C is a right angle, so 90+66=156°
Hope this helped!
