Question

Frank plants a rectangular vegetable garden with a perimeter of 39 meters. The length is twice the width. Find the dimensions of the garden?

Answer 1

39 * (39*2)

Answer 2

let width = w
length = 2w (since it's twice the width)

the perimeter of the rectangle is 39 so \[39 = l + l + w + w \implies 39 = 2w + 2w + w + w \implies 39 = 6w\]
solve for w

Answer 3

w=6.5 ?

Answer 4

seems so

Answer 5

now solve for l
