Answer:

Step-by-step explanation:

Since all the answers are 100s I assume the sizes are 10, 10 and 20.

This would mean there are 2 sides of 10x10 and 4 of 10x20

The total area would be 2*100+4*200=1000. Since that's obviously not one of the answers. We can assume it's probably 15 since it should give us a full 100 number. We know the other two are probably 10 due to their sizes and them obviously being two digits. This would mean it would be 2*100+4*150=800
