Question

Quadrilateral A has side lengths 8, 16, and 12. Quadrilateral B is a scaled version of Quadrilateral A with a scale factor of 0.75. What are the side lengths of Quadrilateral B?

Answer 1

perimeter of Quad A

=

6

+

9

+

9

+

12

=

36

method 1

Quad B the shortest length is 2 so all lengths have been scaled down by a scale factor of 3

Perimeter Quad B

=

2

+

3

+

3

+

4

=

12

method 2

scale factor of linear measurements is 3

perimeter Quad B

=

36

÷

3

=

12
