    Its area becomes 25 times greater, and perimeter becomes 5 times greater.

    I don't think that works for the perimeter. We could try it and see.

    well if its area is 25 times bigger it has to be that answer

    because its the only one that states the area is 25 times bigger

    So how many times bigger is the new perimeter?

    5 times bigger yeah

    Yes. You see, the thing is in the case of the area, we makes the length 5 times bigger and the width 5 times bigger and then we multiply the 5w and 5l which means we have to multiply 5 times 5 and l times w. So the area becomes 25 times bigger.

    But in the case of the perimeter we only add them so we don't have to multiply the 5 by the 5.
