Cumulative problem

Question

Quadrilateral A has side lengths 6,9,9 and 12. Quadrilateral B is a scaled copy if Quadrilateral A, with its shortest side of length 2. What is the perimeter of quadrilateral B?

Answer 1

Since 2 is one-third of 6, the sides of B are all one-third as long as the corresponding sides of A.

Perimeter of B = (1/3)(Perimeter of A) = 12
