Width of the rectangle = 21 ft

Area of the rectangular vegetable garden = length × width

                                                                      = 32 × 21

Area of the rectangular vegetable garden = 672 square feet

Area of backyard not used

       = Area of backyard – Area of the triangle + Area of the rectangle

       = 8688 – 224 – 672

       = 7792 square feet

Area of backyard is not being used 7792 square feet.
