Answer:
B
Step-by-step explanation:
We simply find the area and then multiply that by $1.5 to get our answer.
We need to break down the composite figure and add up each individual area to get total area.
To the right, we will have a trapezoid with bases:
base 1 (top) = 31 - 9 = 22
base 2 (bottom) = 12 (given)
and
height = 9 + 3 = 12
Putting into trapezoid area formula we have:
Also, the left side, we have a skinny rectangle with height 3 and length 9. Thus, the area is:
3 * 9 = 27
Total area is 204 + 27 = 231
Each square feet is $1.50, hence total cost = 231 * 1.5 = $346.50
B is the right answer.
