Answer:
B. 736.
Explanation:
To make things easier, you can add all the lengths of the bigger rectangles and multiply that by 20. When you do this, you get 20 * 32 = 640. Now you find the area of the two smaller rectangles. 12 * 4 = 48. 48 * 2 = 96 (since there are 2 of the smaller rectangles). Add 96 and 640 and you get 736. Hope this Helps!
