Answer:

AB=6 Units

Explanation:

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

  • A'B' = 15 Units
  • B'C' = 9.5 Units
  • BC = 3.8 units

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


D$ilation Factor =(B'C')/(BC) =(9.5)/(3.8) =2.5

Therefore:


(A'B')/(AB) =2.5\\\\(15)/(AB) =2.5\\$Cross multiply \\ 2.5 AB =15 \\AB=15 / 2.5\\$Therefore, AB=6 Units
