2. We would like to thank our math's teacher
Mrs. Sushma Singh for giving us the task of
making this project and for giving us her
guidance.
We would also like to thank to each and
every member of our group as each of them
has contributed in making this project.
Besides them our other classmates also
helped us so a big thanks to them also.
4. In This project we have represented data in
different forms. Then we represented the given
data in form of raw data , frequency table, tally
marks , bar graph and frequency table. We have
also calculated mean , mode and median. In this
way we can arrange different kinds of data in a
sustainable form.

13. Raw data
Length of blackboard = 49 cm.
Breadth of backboard = 96 cm.
Length of window = 52 cm.
Breadth of window = 142 cm.
Length of classroom = 126 cm.
Breadth of classroom = 249 cm.
14. Area :
Blackboard = 4704 sq. cm.
Window =7384 sq. cm.
Classroom = 31374 sq. cm.
PERIMETER
Blackboard = 290 cm.
Window = 388 cm.

15. By making this project , we got to know about the way of
data handling. We learnt the method of finding mean, mode
and median.
This project also taught us to work together as a group.
We also got a chance to make a power point presentation
on this project which enhanced our computer skills.
So this project was very useful for us and we would like to
make such kind of projects again and again.
