Step-by-step explanation:

Let the breadth of rectangle be b

Let the length of rectangle be l

Therefore l=2b

Perimeter of rectangle = 2*(length+breadth)

=2*(2b+b)=2*3b=6b

Perimeter = 72 meter

Therefore 6b=72 meter

b=72/6=12 meter

Therefore the breadth of rectangle is 12 meter

Answer:

Let breadth=x m

then, length=2x m

perimeter of a rectangle=2(l+b)

=2(x+2x)

therefore 2(x+2x)=72

2x+4x=72

6x=72

x=72/6

x=12 metre is your answer
