The other two lengths are #18# and #12#

Explanation:

Similarity in simple words means that two objects have the same shape But, have different sizes.

We can find the other two sides using the proportionality of the first corresponding sides

Consider the diagrams

Use the proportionality

#:.color(blue)(24/12=x/9=y/6#

Solve for #x/9#

#rarr24/12=x/9#

#rarr2=x/9#

#color(green)(rArrx=9*2=18#

Solve for #y/6#

#rarr24/12=y/6#

#rarr2=y/6#

#color(green)(rArry=6*2=12#
