Answer:
560 +32x
Explanation:
There are a number of ways the area can be subdivided. In order to minimize the number of expressions involving x, we choose to divide it this way:
Create a rectangle 52 yd by 40 yd that encloses the figure along with the empty space above the left side of the figure.
Subtract a rectangle whose dimensions are (40-x) by (52 -20) in the upper left corner of the previous rectangle.
Subtract a rectangle whose dimensions are 10 by 24 in the center of the figure.
Then the total area of the parking lot is ...
52·40 -(40-x)(32) -10·24 = 2080 -1280 +32x -240 = 560 +32x
The area of the parking lot is 560+32x square yards.
