The vertices of a rectangle are at (-3,1), (-1,3), (3,-1), and (1,-3). Find the area of the rectangle.
not understanding it right now
|dw:1365368689384:dw|
Since you are told this is a rectangle, the area is L*W
|dw:1365368725722:dw| calculate DC and AD i.e. length and breadth then area of rectangle = l x b

|dw:1365369143033:dw| You can call a side L, like I did in the figure. Then an adjacent side is W. Use the distance formula with the endpoints to find the lengths of L and W. Then multiply them together to get the area.
