Draw Polygons on Coordinate Plane Practice Test

On a coordinate plane, a rectangular dog park has corners at $A(2,1)$, $B(7,1)$, $C(7,5)$, and $D(2,5)$. Plot the points, connect them in order, and close the polygon. What is the perimeter of the dog park?

On a coordinate plane, plot the points $A(-3,-1)$, $B(2,-1)$, $C(2,3)$, and $D(-3,3)$. Connect them in order $A\to B\to C\to D\to A$ to form a rectangle. What is the perimeter of the rectangle in units?
