2-32.

On graph paper, graph the rectangle with vertices at $(2, 1)$, $(2, 5)$, $(7, 1)$, and $(7, 5)$. 2-32 HW eTool (Desmos) Homework Help ✎

Look at problem 2-21. The types of graphs are similar.

1. What is the area of this rectangle?

The area is $20$ square units.

2. Shirley was given the following points and asked to find the area, but her graph paper is not big enough. Find the area of Shirley’s rectangle, and explain to her how she can find the area without graphing the points.

Shirley’s points: $(352, 150)$, $(352, 175)$, $(456, 150)$, and $(456, 175)$

The area of Shirley's rectangle is $2600$ square units. To find the length of the two sides, subtract the $x$- and the $y$-coordinates.
