What is the area of the given trapezoid abcd?
a. 28 in2 b. 56 in2 c. 110 in2 d. 112 in2

 The correct option is (B) 56 in².

Step-by-step explanation:  We are given to find the area of the trapezoid ABCD shown in the figure.

We know that

AREA of a trapezoid with length of the parallel sides a units, b units and height h units is given by

For the given trapezoid ABCD, we have

a = AB = 6 in,  b = CD = 22 in   and    height, h = 4 in.

Therefore, the AREA of trapezoid ABCD is given by

Thus, the required area of the trapezoid ABCD is 56 in².

Option (B) is CORRECT.
