What do you mean by "largest" ???
Do you want the widest rectangle ?
The longest rectangle ?
How about the rectangle with the most area ?
The length can be anything less than 20 ft, and the width can be anything less than 20 ft.
Any of those shapes will have an area greater than zero.
The rectangular garden with the greatest possible area is a square, 10 ft x 10 ft.
Its area is 100 square feet.
A square 14 ft on a side.
10' X 10' = 100 sqft. The more you deviate from a square, the smaller the area will be. If you change the sides by 1 foot, you are left with 9 X 11 which is only 99 sqft. If you make the rectangle long and narrow, 19 X 1 is only 19 sqft.
