Question

If two rectangles are similar and the first rectangle has length of 10 inches and height of 12 inches and the second rectangle has

length of 30 inches, find the height of the second rectangle.

Answer 1

36 inches.

Explanation:

Write the rectangles as ratios.

First= 10:12

Second= 30:x

You can see that the second is 3 times as large as the first. Therefore, the second height must be 12*3. 12*3=36
