Answer
72 in.
Work Step by Step
From the given figure , We need to find out the area of the parallelogram ABCD
In parallelogram opposite sides are equal so AB = CD = 12in
By theorem 8.1.2 The area A of a parallelogram with a base of length b and corresponding altitude of length h is given by A=bh
From the given figure AB= 12 in
altitude = 6 in.
therefore area of parallelogram = bh
= 12 * 6 = 72 in.
