275 units^2

Step-by-step explanation:

The formula for the area of trapezoid is:

Area=((b1+b2)/2)*h

In the given trapezoid, as it can be seen

b1=16

h=11

The lower base will be calculated using all the lengths in the lower base

b2=9+16+9

b=34

Putting the values in formula

Area=((16+34)/2)*11

Area=(50/2)*11

Area=25*11
