I know that that I have to multiply base times the height but I don't know how to find the area for this particular figure.

anonymous · Answer

base time height minus the area of the missing triangle 
9*9 - 1/2( 5*4)=81-10 = 71

Ohhhhhh okay! Thanks so much! That makes A LOT of sense now! I never would have thought of that. Thanks! I go to online school and they don't explain things very well :p
