    If diagonals are 20 cm& 11cm Then Area= (1/2) *20*11=110 cm^2

    ( Sides means more details required)

    If parallel sides are 20 & 11, then perpendicular ( distance between parallel sides) will be 20/2 +11/2 = 15.5 cm

    Then area= {20+11}/2 * height = (31/2) *15.5 cm =240.25 cm^2

    I assign my students a simple math question. Then I go to YA and see that exact question online. Do I fail the student or do I simply let the board of ethics expel the student? Find the right course of action?
