How many times will the perimeter decrease and how many times will the area of the rectangle decrease

How many times will the perimeter decrease and how many times will the area of the rectangle decrease if it is reduced three times on each side?

The perimeter will change 3 times, and the area 9 times
For example, let’s take a rectangle with sides 12 and 9
Its perimeter = (12 + 9) * 2 = 42
Its area = 12 * 9 = 108
And now we will reduce the sides of this rectangle by 3 times, which means there will be a rectangle with sides 4 and 3
Its perimeter = (4 + 3) * 2 = 14
Its area = 4 * 3 = 12

Compare
Perimeter changed: 42: 14 = 3 times
Area changed: 108: 12 = 9 times
