The two rectangles are similar. Which is the correct proportion for?

To find the correct proportion for two similar rectangles, we need to compare the corresponding sides of the rectangles.

If the lengths of the sides of the first rectangle are a and b, and the lengths of the corresponding sides of the second rectangle are x and y, then the correct proportion for the two rectangles is:

a/x = b/y

This means that the ratio of the lengths of the sides of the first rectangle to the lengths of the corresponding sides of the second rectangle should be equal for all pairs of corresponding sides.

So, to find the correct proportion for the two similar rectangles, calculate the ratio of the lengths of the sides and make sure it is the same for all pairs of corresponding sides.
