    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.
