Art and Crafts
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.
