We started something new and I'm competely lost

Given:

Triangle ABC is similar to triangle XYZ.

The measures of the sides are AB = 6 cm, BC = 18 cm and XY = 12 cm

We need to determine the measure of side YZ.

Measure of YZ:

Since, ABC and XYZ are similar triangles, by using similar triangles property, we have;

Let the length of YZ be x.

Substituting the values, we get;

Cross multiplying, we get;

Dividing both sides by 6, we have;

Thus, the value of x is 36.

Hence, the measure of the side YZ is 36 cm.
