The sun roof in Troy’s house is shaped like a rectangle. He increases the length of the sides of the sun roof to three times the existing ones. How will this change affect the perimeter of the sun roof?

    It will be 12 times the original perimeter. It will be 3 times the original perimeter. It will be 18 times the original perimeter. It will be 9 times the original perimeter

    okay, so he increases the length and makes it three times. perimeter originally = 2(l+b) now 'l' becomes '3l', so what will be the new perimeter?

    No, it would not necessarily a multiple of the previous perimeter - since the breadth is not known.

    Wait - did you actually mean 'area' instead of 'perimeter'?
