Solve for the equation. The. Divide by 4 on both sides. And whatever you get for the slope. Write the opposite which will give you the perpendicular slope. For example: 1/4x is perpendicular to -4x
I would say 7/24 because when you multiply it you should be able to get a large number.
To have a different rectangle with the same perimeter you just have different measurements. If you need an example let me know!
