Question

Find the area in square metre and Square centimetre of a 20 m long and 1800cm wide room

Answer 1

Answer:

Area = length * breadth

= 20m * 18m

= 360 sqm

Area = 2000cmx1800cm

= 3600000 sq cm

Explanation:

Answer 2

The area in square meter is  360 m² and Square centimeter is 3600000 cm².

To find : Area in square meter and square centimeter

Given :

Length = 20 m.

Breadth = 1800 cm.

Formula :

1 m = 100 cm.

1 cm = $\frac{1}{100}$ m.

Area in square meter = Length × Breadth

Length = 20 m  ;  Breadth = 1800 cm = 1800 × $\frac{1}{100}$ = 18 m      

                                        = 20 × 18

                                        = 360 m²

Hence, the area in square meter is 360 m².

Area in square centimeter = Length × Breadth

Length = 20 m = 20 × 100 = 2000 cm  ;  Breadth = 1800 cm

                                           = 2000 × 1800

                                           = 3600000 cm².

Therefore, area in square meter is 360 m² and the area in square centimeter is 3600000 cm².
