STEP-BY-STEP SOLUTION:
To begin with, let's established the formula for the area of a trapezoid / trapezium as displayed below:
A of trapezoid = [ h ( a + b ) ] / 2
Now, let's substitue the values from the equation into the formula and then solve accordingly as displayed below:
h = 4
a = 6
b = 22
A = [ h ( a + b ) ] / 2
A = [ 4 ( 6 + 22 ) ] / 2
A = [ 4 ( 28 ) ] / 2
A = 112 / 2
A = 56 in2
Therefore, the answer is:
Option B. 56 in2
