Question

Carlos downloaded a pattern from the Internet for making atable with an irregular polygon-shaped top. The instructionson the pattern say that the scale factor is 3. The sides of thepattern are shown on the diagram below. What is the length ofthe longest side of the finished tabletop?5 in11 in6 in5 in7 in

Answer 1

From the question;

The longest side of the polygon is 11 in

and the scale factor is 7/2.

Therefore

$\begin{gathered} \text{The longest side of the table = 11in }\times\text{ }\frac{7}{2} \\ \text{The longest side of the table = }\frac{77\text{ in}}{2} \\ \text{The longest side of the table = 38.5 in} \end{gathered}$

Therefore the correct answer is option C
