How could you find the measurements of the garden with a perimeter of 60 feet and the greatest possible area?

P = 2L + 2W

A = LW

If the garden is a square >> 60 / 4 = 15
Area = 15 * 15 = 225 sq. ft.

Let's try a different set of dimensions.

A = 10 * 20
A = 200 sq. ft

What would you add to 2/3 to get a sum of 1?
