Question

lenght 2m 12cm breadht 30m​

Answer 1

Answer:

Step-by-step explanation:

length= 2m 12cm

Breadth= 30m

we know that 1 m=100 cm so,

2m12 cm=200+12=212cm

and 30m=100×30=3000cm

therefore perimeter of rectangle=2(l+b)

=2(212+3000)

=2(3212)

=6424cm

Answer 2

Answer:

∆ 7,20,000cm or 7200m

Step-by-step explanation:

First convert it to cm:

[1m = 100cm]

•2m = 200cm

•12cm = 12cm

•30m = 3000cm

Volume formula = l×b×h

Volume => 200 × 12 × 3000

Volume => 7,20,000cm or 7200m
