The length of a rectangle is six times its width. if the area of the rectangle is 384 yd2, find its perimeter.

Width = w

lenght = 6 width = 6w

area = 284 yd²

= (width) (length)

= (w) (6w)

= 6w²

6w² = 284

w² = 284/6

= 47.333333 ...

w=√47.2

= 6.88 inches

perimenter = 2width + 2 lenght

= 2 (w) + 2 (6w)

= 2w+12w

= 14w

= 14 (6.88)

= 96.28 inches
