What is the Area of a Rectangle?
Area of a Rectangle = (length)(width)
A rectangle has two opposite sides that are equal and parallel to each other. Therefore, the point of the fourth coordinate that would make ABCD a rectangle is (7, 2).
Area = (AB)(BC)
AB = 5 units
BC = 9 units
Area of rectangle ABCD = (5)(9) = 45 units squared.
