0 votes 0 votes Angle C and D will be right angles BC will be 9 cm (Applying Pythagoras theorem) AD will be 12 cm (Applying Pythagoras theorem) Area of the quadrilateral = Area of triangle ABC + Area of triangle ABD = 54 + 54 = 108 cm square mudit23june answered Jun 28, 2017 mudit23june 346 points comment Share See all 0 reply Please log in or register to add a comment.
