Question

Figure ABCD has vertices A(−4, 1), B(2, 1), C(2, −5), and D(−4, −3). What is the area of Figure ABCD?

Answer 1

keep in mind, when a quadrilateral has only two paralle sides, or bases, is a trapezoid, and the sides that are parallel, are the so-called "bases", and the distance between both of them, is the altitude or height

notice the picture below

and surely you'd know how long the height and each base are
