For a rectangular fish pond,its width is 6 meters shorter than the length and the length is twice as long as the width,then what is the perimeter of this fish pond?

Solution:

length - width = 2 width - width = width = 6 m

perimeter = 2 x ( length + width)

= 2 x 3 width

= 2 x 3 x 6

= 36 ( m )

So,the perimeter of the fish pond is 36 meters.
