Answer:
20
Explanation:
The grid lines are 1 unit apart, so you can determine the dimensions of the trapezoid by counting grid squares. The parallel bases have lengths 6 and 2. They are 5 units apart.
The area is given by ...
A = 1/2(b1 +b2)h
A = 1/2(6 +2)(5) = 20
The area of the trapezoid is 20 square units.
