Answer:

AB=6 Units

Step-by-step explanation:

Given the following lengths of rectangle ABCD and its dilation A'B'C'D' respectively

We are to determine the length of AB. To do this, we first determine the dilation factor.

$D$ilation Factor =\dfrac{B'C'}{BC} =\dfrac{9.5}{3.8} =2.5$

Therefore:

$\dfrac{A'B'}{AB} =2.5\\\\\dfrac{15}{AB} =2.5\\$Cross multiply \\ 2.5 AB =15 \\AB=15 \div 2.5\\$Therefore, AB=6 Units$
