A rectangle on the coordinate plane has vertices (–3, 1), (–3, 5), (2, 5), and (2, 1). Plot the vertices on the graph.Which expression can you use to find the area of this rectangle?

The rectangle’s horizontal side runs from x = −3 to x = 2, so its length is 2 − (−3) = 5 units. Its vertical side runs from y = 1 to y = 5, so its width is 5 − 1 = 4 units. Area is length × width, so use 5 × 4, choice B.
