__PERIMETER AND AREA__

** **

**Learning Objectives**

● To understand the concept of perimeter and area
of closed shapes.

● To calculate the perimeter and area of square,
rectangle, right angled triangle and their combined shapes.

● To understand the usage of units appropriately
for area and perimeter.

**Introduction**

We come across many situations in our day to day
life which deal with shapes, their boundaries and surfaces. For example,

● A fence built around a land.

● Frame of a photograph.

● Calculating the surface of the wall to know the
quantity of the paint required.

● Wrapping the textbooks and notebooks with brown
sheets.

● Calculating the number of tiles to be laid on
the floor.

Some situations need to be handled tactfully and
efficiently for the following reasons.

● Using the optimum space to build a dining hall,
kitchen, bedroom etc., in constructing a house in the available land and planning
of materials required.

● Arranging the things like cot, television, cup-board,
table etc., in the proper place within the available space at home.

● Reducing the expenses in all the above activities.

In this context, learning of perimeter and area
will be of great importance.

**Think about the situation**

Apoorva and her brother return from school. Their
mother serves them some biscuits. While they eat them one by one, Apoorva arranges
the biscuits on a tray. She finds that the tray can hold only 12 biscuits. If she
has to extend spreading the remaining biscuits also in the same manner, she will
need a bigger tray in size because, already 12 biscuits occupied the surface of
the tray completely. The total length of the visible borders of the tray is said
to be the ** perimeter** and the surface
occupied by the biscuits is said to be the
