-- The smallest perimeter is about 24.98 feet ... that's 4 √39 .

-- There is no 'greatest'. If somebody gives you a gigantic perimeter
with an area of 39 square feet, I can always make a rectangle with the
same area and a bigger perimeter.

Example:

3-ft by 13-ft . . . Area = 39 ft² . . . Perimeter = 32 feet

1-ft by 39-ft . . . Area = 39 ft² . . . Perimeter = 80 feet

6-in by 78-ft . . . Area= 39 ft² . . . Perimeter = 157 feet

1-in by 468-ft . . Area = 39 ft² . . . Perimeter = 936-ft 2-in

0.1inch by 4,680-ft . . Area = 39 ft² . . . Perimeter = 9,360-ft 0.2-inch

<h2>For x=2</h2>

- 10(2) + y = 4

- 20 + y = 4

y = 24

<h2>For x=1</h2>

- 10( 1) + y = 4

- 10 + y = 4

y = 14

<h2>For x=0</h2>

- 10(0) + y = 4

0 + y = 4

y = 4

<h2>For x=-1</h2>

- 10( - 1) + y = 4

10 + y = 4

y =  - 6

<h2>For x=2</h2>

- 10( - 2) + y = 4

20 + y = 4

y =  - 16
