The polygon with the shortest perimeter for a given area is a regular polygon. The regular 4-sided polygon is the square.
The side length of the square with an area of 100 ft² is √(100 ft²) = 10 ft.
The rectangle with the minimum perimeter for an area of 100 ft² is 10 ft by 10 ft.
I can see the question but if you add a picture maybe i’ll understand it a little more
It’s the first one! The table shows X going up and Y going down, so the slope would be negative!
