Question

The sides of a quadrilateral are 3, 4, 5, and 6. Find the length of the sides of a similar quadrilateral whose area is 9 times as great. Put your answer in the same order as the question.

Answer 1

If the area is larger by a factor of 9, then the side lengths are larger by a factor of \[\sqrt{9}=3\]
Basically, you multiply every number by 3.
