Arectangle has a width of 4 inches and the length of 6 inches a similar rectangular has a width of 12 inches what is the length of the similar rectangle

The length of the similar rectangle is 18 inches.

Step-by-step explanation:

Similar figures have the same ratio of corresponding side lengths.  In this example the width of the first rectangle is 4 inches, while the width of the second rectangle is 12 inches.  We can compare them by setting up the fraction 4/12, which can be simplified to 1/3.  So, the ratio between the similar rectangles is 1:3.  If the length of the first rectangle is 6 inches, in order to find the length of the second rectangle, we would simply multiply by 3.  So, 6 x 3 = 18, which is the length of the second rectangle.
