What is the area of the trapezoid?

234

Step-by-step explanation:

A=a+b

2h=10+26

2·13

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
