Tell us what’s happening:

Hi!
Code is failing on step 20: Rectangle(15,10).get_amount_inside(Square(5)) should return 6.

My code is definitely returning 6 with this input. Every other test passes - when F12ing the assertion error states 0 != 6. Not sure exactly what the issue is.

Thanks in advance

Your code so far

try this

rect = Rectangle(3, 6)
sq = Square(5)
rect.set_height(10)
rect.set_width(15)
print(rect.get_amount_inside(sq))

figure out why it’s not working

Thank you! I added lines to the setters for height and width which re-calculated the area and it passed - is this the best/most intuitive way to do this?

it’s a way, at this point of your learning journey, focus on writing things that work
