Answer:
I believe from A to B would be 12.50
Step-by-step explanation:
On the top, the equation would be 3 (height) times 3(one of the lengths) times (3 times 5 divided by two parenthesized) (which equals 7.5) = 67.5. On the bottom half, we take 9 times 7 = 63, plus the 67.5, which equals 130.5. The best way to get to the answer from here is to expand the overall equation by halves (ex. 3 x 3 x 7.5 + 9 x 7 x .5 or then to 3 x 3 x 7.5 + 9 x 7 x 1, 1.5 2, etc.) This numbers got closer and 3 x 3 x 7.5 + 9 x 7 x 12.5 (12.5 being the AB length)
TL;DR: 3 x 3 x 7.5 + 9 x 7 x (12.5) = 855
AB
Sorry if this was a bit confusing.
