Drawing polygons with coordinates challenge

More challenging problems involving drawing shapes on the coordinate plane.


TV screen measurements refer to the diagonal distance across the screen, so a 50-inch TV would not be 50 inches wide or 50 inches high. When Claudia measured her parents' new 50-inch TV, she found that its screen was a rectangle 40 inches wide by 30 inches high.
Draw the TV screen in the coordinate plane with the upper-left corner at left parenthesis, minus, 20, comma, 15, right parenthesis and the longer sides parallel to the x-axis.
(The units of the graph are in inches.)
