On a coordinate plane, parallelogram p q r s is shown. point p is at (negative 2, 5), point q is at (2, 1), point r is at (1, negative 2), and point s is at (negative 3, 2).
in the diagram, sr = 4 startroot 2 endroot and qr = startroot 10 endroot. what is the perimeter of parallelogram pqrs?
startroot 10 endroot units
8 startroot 2 endroot + 2 startroot 10 endroot units
16 startroot 2 endroot units
8 startroot 2 endroot + 8 units
