For this case, what you must do is find the area of the two rectangles shown in the figure.
We have then:
Rectangle 1:
A1 = (40) * (18)
A1 = 720
Rectangle 2:
A2 = (24-18) * (40-30)
A2 = (6) * (10)
A2 = 60
The area of the composite figure is:
A = A1 + A2
A = 720 + 60
A = 780 feet ^ 2
Answer:
the area of the figure is:
C. 780 ft ^ 2
