Calculate the area of the irregular polygon shown below:

a) 45 inches squared
b) 50 inches squared
c) 60 inches squared
d) 85 inches squared

So the way I'd do this is by figuring out the two missing rectangles, and then taking them away from the total area. The total area would be 10 × 12 = 120 inches, and the two rectangles would be 5 × 7 = 35, 35 × 2 = 70. Now, you just do 120 - 70 = 50 inches squared, which is your answer. I hope this helps!
