Answer:

The parallel sides are called the bases of the trapezoid

Step-by-step explanation:

[tex]area = (\frac{a + b}{2}) \times h[/tex]

       [tex]= \frac{14.1+22.7}{2} \times 18\\\\=331.2 \ unit^2[/tex]

Answer:

331.2 units^2

Step-by-step explanation:

There is a formula for the area of a trapezoid of legs a and b and width h:

a + b

----------- * h

     2

Here the leg lengths (which are parallel) are 14.1 and 22.7, and the width is 18.  Thus, the desired area is

14.1 + 22.7                        36.8

---------------- * 18  =  A  = ------------ * 18 = 331.2 units^2

       2                                   2

The dimension 20.3 is not needed here.
