Two rectangles are similar. One has a length of 13 cm and a width of 10 cm, and the other has a width of 7 cm. Find the length of the second rectangle. Round to the nearest tenth if necessary.

Step 1. Two rectangles are similar when the sides are in the same proportion.

Step 2. That is, where L is the length of the second rectangle

Step 3. Solving for L by multiplying 7 to both sides of the equation in Step 2 yields cm

Step 4. ANSWER: The length of the second rectangle is 5.10 cm.

I hope the above steps were helpful.
