In the given figure BC = AC, angle AFD = 40° and CE = CD. The

value of angle BCE = ?

Each side of a given polygon is parallel to either the X or the Y axis. A corner of such a polygon is said to be convex if the internal angle is 90^o or concave if the internal angle is 270^o. If the number of convex corners in such a polygon is 25, the number of concave corners must be 

Two sides of a plot measure 32 meters and 24 meters and the angle between them is a right angle. The other two sides measure 25 meters each and the other three angles are not right angles.What is the area of the plot?
