Answer 3

i want to know how to do it so if i have a question like this i will know how to do it

Answer 4

so perimeter is width + width + length + length. So two of the lengths will be the same. That means that 90 = Width + Width + 15 + 15. So 90-30 = Width + Width.90-30 is 60. And assuming both the widths are the same,you divide 60 by two,which gives you 30.
