The area of a rectangle is it's length times it's height. We are given polynomials for these values, so we can multiply them using the FOIL method to find the area.
FOIL stands for Firsts, Outers, Inners, Lasts. This means we multiply the first term of each polynomial together, the outer terms together, the inner terms together, and the last terms together.
(2x+5)(x-2)
The first terms are 2x and x, the outer terms are 2x and -2, the inner terms are 5 and x, and the last terms are 5 and -2:
2x^2 - 4x +5x - 10
Combine like terms:
2x^2 + x - 10
The third option is the correct answer.

Answer:
1386
Step-by-step explanation:
If you have trouble with that, you can multiply 66 by 20, then 66*1, and add them (break apart the 21.)
4 × 1 × 3 = 12
2 × 1 × 3 = 6
12 + 6 = 18 cubic ft
