The length of a rectangle is twice its width.
If the area of the rectangle is 72 in“, find its perimeter.

according to tje question

length(l)=2x

breadth(b)=x

then,

to find perimeter

p=2(l+b)

or,72=2(2x+x)

or,72=2×3x

or,72=6x

or,72÷6=x

or,12=x

then,

length(l)=2x=2×12=24in

breadth(b)=12in

the answer is 36in
