maksim [4K]

Answer:

$CD=6\frac{2}{3}\ units$

Step-by-step explanation:

we know that

If rectangle ABCD is similar to rectangle ZBXY

then

the ratio of their corresponding sides is equal and is called the scale factor

so

$\frac{BC}{BX}=\frac{CD}{XY}$

in this problem we have

$BC=10\ units$

$BX=6\ units$

$XY=4\ units$

Substitute the values and solve for CD

$\frac{10}{6}=\frac{CD}{4}$

$CD=4*10/6$

$CD=20/3=6\frac{2}{3}\ units$
