let us take width as x
length=2×width=2x

Perimeter of plot=300m
so 2(l+b)=300
2(2x+x)=300
3x=300/2
3x=150
x=150/3
x=50
so length is=2x
=2×50
=100m
width=50m

area of rectangle=l ×b
=100m×50m
=5000m square.

ankushrahmi123: HEY UTPALA DO KIT AND POST

utpalachoubey63: it's all right

Answer:

StStep-by-step explanation:

Let breadth of room(b)=x

Now,length of room(l)=2b=2x

And height of room(h)=l/3=2x/3

Now,Volume of air in room=Volume of room(V)

So,V=972 cubic m

We know,Volume of cubiod=l*b*h

So,V=2x*x*(2x/3)=972

=>4x^3/3=972

=>x^3=729

=>x=9

So,b=9m

l=2*8=18m

h=2*9/3=6m

utpalachoubey63: what have u done

utpalachoubey63: where is the volume in question?

ankushrahmi123: HERE 972 CUBIC METER AIR IN ROOM

ankushrahmi123: THEN UNIT OF VOLUME IS CUBIC METER

ankushrahmi123: OK
