So first what you do is measure one of the sides for example maybe it could be 10 cm and then measure the other side (the one that is diffrent) for example it could be 5 cm So then all you need to do is times the two numbers (10cm) by two and do the same with the other number (5cm) and then just simply add the two numbers.
