Asked by Chris

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?
Answered by Reiny
Did you plot the points?
I would expect you to recognize that the shape is a rectangle.
Just count the distances.
Answered by Chris
Is there a way to mathematicaly solve it without plotting it?
Answered by Steve
well,
PQ = RS = 3
QR = SP = 4

so the perimeter is 2(3+4) = 14
