Short side is 4, long side is 8.
Math: I made a rectangle with double the area. I took that number and found the multiples. 1x32, 2x16, 4x8. 4 is half of 8, so its the shorter side.
All of those numbers have a common factor, which is 3. So you divide all of their values by 3.
3:9:15:24
=1:3:5:8
Because the values cannot be divided anymore, this ratio is in it's simplest form.
No, it is not. This is because there is only one variable, instead of two.
