                       We all  enjoy  art and crafts. Do you  know that
                       when you draw a picture or make a craft, you

                       use mathematics! Art and crafts help us develop
                       our imagination as well as creativity.

                       Nupur  and  Nikhil  are  drawing  pictures  of
                       Mahatma  Gandhi.  After drawing, they  want to
                       decorate  the boundaries  of their pictures with
                       coloured ribbon. To find the measurement of the
                       ribbon, they measure the length of each side. The

                       measures are shown along the sides. Help them
                       find the length of ribbon required for each picture.
