Answer:

773 or 278.5 (if it only wants the sides the pic shows)

Explanation:

13*5=65

65/2=32.5 (since it is a triangle you by 2)

12*9=108

108/2=54

15*20=300 (it is a square so you leave it)

you do it on the other sides that you can't see in the pic.

Add all the numbers together: 32.5+32.5+54+54+300+300 or 32.5(2)+56(2)+300(2)=773

Hope this helps!
