Question

A man wants to enclose a rectangular garden adjacent to a river. The length of the rectangle is two times the width. How many linear feet of the fence must he buy if he does not need fencing along the river and the perimeter of the rectangle is 240 feet?

Answer 1

200 160

Explanation:

if the perimeter is 240, the length is 80 and width is 40.

40+80+80=200

80+40+40=160

Answer 2

200, 160

Explanation:

if perimeter is 240 it means sides are 40 by 80.

if he does not need to place fencing on one side, they remove one 80 or 40,

40+80+80=160 or 40+40+80=200
