Question

quadrilateral a has side lengths 3, 4, 5, and 6. quadrilateral b is a scaled copy of quadrilateral a with a scale factor of 2. select all of the following that are side lengths of quadrilateral b. a. 5 b. 6 c. 7 d. 8 e. 9

Explanation:

Step1: Multiply side - lengths of A by scale factor

When we have a scaled - copy with a scale factor of $k$, we find the side - lengths of the new figure by multiplying the side - lengths of the original figure by $k$. Here, $k = 2$, and the side - lengths of Quadrilateral A are 3, 4, 5, and 6. So the side - lengths of Quadrilateral B are $3\times2=6$, $4\times2 = 8$, $5\times2=10$, and $6\times2 = 12$.

Answer:

B. 6, D. 8
