Question

Q6. Find the area in square metre of a piece of cloth 1 metre 25 cm wide
and 2 metre long.​

Answer 1

Length of the cloth = 2 m

Breadth of the cloth = 1 m 25 m

Breadth of the cloth = 1 m + 0.25 m

Breadth of the cloth = 1.25 m

(Since 25 cm = 0.25 m)

Area of the cloth = length of the cloth × breath of the cloth

=> Area of the cloth = 2 m × 1.25 m

=> Area of the cloth = 2.50 sq m

Hence:-

The area of the cloth is 2.50 sq m.

More Information:

The amount of surface enclosed by a closed figure is called its area.

To calculate the area of a figure using a squared paper, the following conventions are adopted:

Ignore portions of the area that are less than half a square.

If more than half a square is in a region. Count it as one square.

If exactly half the square is counted, take its area as ½ sq units.

Area of a rectangle = length × breadth

Area of a square = Side × Side

GiVeN :-

• Width of a piece of cloth = 1m 25cm

→ 1m 25cm

→ 1m (25/100) m

→ 1m 0.25m

→ 1.25 m

• Length of the piece of cloth = 2m

╰➝ Area = Length × Breadth

╰➝ Area = 2 × 1.25

╰➝ Area = 2.50 m²
