Answer:
33
Explanation:
You find the area of each triangle and that is (4*3)/2 which is equal to 6 but because all four sides are the same size you would multiply 6 by 4 so 6*4=24 you must also find the area of the bottom and that would be 3*3= 9 then you'd add them together 24+9=33 i hope that this helps!
