from which
1 | object.width object.width = - (object.width * 0.2) |
from which
1 | object.width = object.width * (1-0.2) |
For the height is exactly the same.
When there's a third object, ie there has been given the percentage to be removed from our object, but by a third party, we have:
1 2 3 | rate = object.width / object.height object.width = terzo.width * (1-0.2) object.height = object.width / installments |
