Answer:
234 units^2 = A
Step-by-step explanation:
The two parallel sides of this trapezoid are of length 10 and 26 respectively. The average length of the figure is therefore (10 + 26)/2, or 18 units.
The area of the trapezoid is thus A = (average length)(height), which here is
A = (18 units)(13 units) = 234 units^2 = A
