Rectangle ABCD was dilated to create rectangle A'B'C'D. Triangle A B C D is dilated to form triangle A prime B prime C prime D. Side B C is 3.8 units. Side A prime B prime is 15 units and side B prime C prime is 9.5 units. What is AB? 6 units 7.6 units 9.5 units 12 units

Step-by-step explanation:

Given

Required

Determine the length of AB

Because A'B'C'D is a dilation of ABCD, then the following relationship must exist:

Substitute values for A'B', B'C' and BC

Express the ratio as fractions:

Multiply through by 14
