of the rectangle. The side of the pond will be
8 metres and width will be 5 metres. It will have
a square shape pond on the other side as shown
in the picture. The one side of this pond will be
2 metres. Find the total area of the both ponds.

2. A square shape swimming pool with perimeter
of 440 m also needs to be made. To make it the
floor of the pool has to be tiled. If the cost of the
tiling is ` 300 per metre square, find the cost of
tiling the swimming pool floor.
3. The park will also have a parking space. Each
side of space will have area of 15 square metre.
What will be its dimension?

HOTS
2 m
1. Inside a rectangular park of dimension 60 m by 40 m, a path 2 m wide is built in
the middle, one along the length and other along the breadth. What is the area of 40 m
the remaining part of the park? 2 m
2. Draw (if possible) a polygon inside an equilateral triangle such that the 60 m
(i) area of the polygon is greater than that of the equilateral triangle.

(ii) perimeter of the polygon is greater than that of the equilateral triangle.

Activity

Objective: To distinguish between perimeter and area.
Materials Required: Measuring tape, ruler, chalk, thin rope.

Procedure: 1. The class will be divided into two groups say ‘A and P’ where A stands for area and P stands for
perimeter.

2. The teacher will allow them to work on a patch of land (rectangle or square) in the field. Group
‘P’ will find out the length of rope required to make a boundary.
3. Group ‘A’ will divide the land into squares of equal size (1 m × 1 m) using chalk and find the area
of the land.
