Find the area and perimeter of a rectangle for which (– 2, 2), (7,2), and (7, – 3) are three of the vertices. What is the 4th vertex?

• math -

You could sketch the given points, but ...
just looking at the values, we can see the base runs from -2 to 7, so the base is 9
and the height goes from -3 to 2, so the height is 5
area = 5(9) = 45
perimeter = 2(5) + 2(9) = 28

missing point must be (-2, -3)
