Samantha made a design using two similar quadrilaterals. The smaller quadrilateral has side lengths of 6 cm, 8 cm, 8 cm, and 14 cm. She enlarged it to create a larger quadrilateral using a scale factor that increased the 6-cm side to 9 cm. What is the total length of craft wire Samantha used for both quadrilaterals?
