Answer 1

let the breadth of area of plot be x.

then,length is 2x

Now,area=3200

area of rectangle=l×b

3200=2x × x

3200/2=x2 (square)

1600=x2

x=40.

therefore,the breadth is 40 metres

Answer 2

Let breadth be x

and length be 2x

Then 2x *x =3200

x*x=3200÷2

x*x=1600

x=40

Breadth=40 and Length=80
