Answer:
390
Explanation:
First find the missing side of the top rectangle.
30 - 20 = 10
Now that you know 10 is the missing length, you can find the area for the top rectangle.
10 x 25 = 250
For the bottom rectangle do the same thing to find the area. (Length times Width) (L x W)
7 x 20 = 140
Now, add up both of the areas to find the complete area of the composite shape.
250 + 140 =390
