Question

The vertices of a sandbox are P(12,14), Q(12,17), R(16,17), and S(16,14). The coordinates are measured in feet. What is the perimeter of the sandbox ?

Answer 1

First, you need to draw this out. Roughly, it should look a little something like the link i included in this answer. then u just draw a line tracing the points to make a rectangle (sandbox) and decide that the perimeter, or the distance around, would be 3+4+3+4 = 14 feet.
