Question

Find the area in sq.m and sq.cm of a 20 m long and 1800 cm wide room​

Answer 1

$\large \sf \purple {\boxed {Area\: in\:meter\:square}}$

Area of Rectangle = Length×breath

1m = 100cm

area = 20m × (1800/100)m

= 20m × 18m

= 360 sq. m

$\large \sf \purple {\boxed {Area\: in\:cm\: square}}$

Area = (20×100)cm × 1800cm

= 2000cm × 1800cm

= 3600000 sq cm

Answer 2

Given:-

• Long = 20 m
• Wide = 1800 cm

⠀

To find:-

• Area of room in sq.m and sq.cm.

⠀

Solution:-

Firstly,

• Converting into sq.m.

⠀

→ 1800 ÷ 100

→ 18 m

⠀

☆Area = length × breadth

⇛ l × b

⇛ 20 × 18

⇛ 360 sq.m

⠀

Hence,

• the area of room in sq.m is 360 sq.m.

⠀

Then,

• Converting into sq.cm.

⠀

→ 20 × 100

→ 2000 cm

⠀

☆Area = length × breadth

⇛ l × b

⇛ 2000 × 1800

⇛ 3600000 sq.cm

⠀

Hence,

• the area of room in sq.cm is 3600000 sq.cm.
