Question

Find the area of square of length 4cm. Find the area of a rectangle having length 8cm and breadth 2cm. What is the difference of two areas?​

Answer 1

Step-by-step explanation:

In a square the length is equal to breadth.

Hence, area of a square = side × side

The number of 1 cm squares enclosed = 4

Area = 4 sq cm

4 = 2 × 2

Hence, area = side × side

The unit of sides and the corresponding units of areas as given below:

Unit of Side

          Unit of Area

mm

square mm (sq mm) or mm2

cm

square cm (sq cm) or cm2

m

square m (sq m) or m2

km

square km (sq km) or km2

Note: Write finding the area of a given figure, make sure that the sides (length or breadth) are in the same unit of length. If they are given in different units, change them to the same unit.

Look at the above figure. You can see that the area of a square having sides 2 cm each is equal to the area of 4 squares of sides 1 cm each = 4 cm2. It can also be expressed as 2 cm × 2 cm = 4 cm2. Area of a square is 2 times of its each side.
