What is the total area! pls ! formula: a=1/2bh for triangle and a=bh for rectangle! ty!

100 in^2
20, represents the full base. but the rectangle’s base is 10. both triangles are equal so 20-10 equals 10 and split them evenly on both sides.
6•5=30/2=15
since you have two equal triangles your total answer is 30. then you do 10•7 which is 70.

Google it that might work
