Perimeter of a square is $164 \mathrm{c}\mathrm{m}$. What is its length?  $\mathrm{cm}$.

The perimeter of the base of a square pyramid is $96 \mathrm{cm}$ and its height is $16 \mathrm{cm}$. What is the length of a base edge?

A rope of length $40$ metres is cut into two pieces and two squares are made on the floor with them. The sum of the areas enclosed is $58$ square metre.

What are the lengths of the sides of the squares ?

You know that the area of a figure is the surface covered by it. Find the area of the following figures by counting the squares. Each squares of area $1 \mathrm{sq}.\mathrm{cm}$

Find the area of the following figure by counting the squares of unit area.

Find the area of piece $\mathrm{B}$.

You know that the area of a figure is the surface covered by it.Find the area of the following figure by counting the squares. Each square of area $1 \mathrm{sq}.\mathrm{cm}$

Look at these interesting stamps.

How many squares of one centimetre side does stamp $\mathrm{A}$ cover?

And stamp $\mathrm{B}$? 

Find the area of the following figure by counting the squares of unit area.

The length of piece A is $6 \mathrm{cm}$.

So $6$ squares of side $1 \mathrm{cm}$ can be arranged along its length.

The width of piece A is $5 \mathrm{cm}$.

So $5$ squares can be arranged along its width.

Altogether how many squares can be arranged on it?

Look at the below figure carefully.

Which stamp has the biggest area$?$

The squares of side is $1 \mathrm{cm}$.

The area of biggest stamp is $18 \mathrm{sq}.\mathrm{cm}$.
