Answer:
Area = 100 units^2
Explanation:
This shape is a trapezoid. The area of a trapezoid is:
A = 1/2(Base+Base)•h
What you do is average the bases and times by the height. The only thing is in your picture the bases are the 12 and 8. And the height is the 10.
Area = 1/2(12+8)•10
= 1/2(20)•10
= 10•10
= 100
The area is 100 square units.
