You by 2 picture frames that are similar the ratio of the corresponding side lengths is 4 : 5. what is the ratio of the areas?

For this case we have:

Let:

l1, l2 the sides of the first frame

l1 ', l2' the sides of the second frame

We have as information the following:

, then

, then

On the other hand,

The area of table 1 is given by:

The area of table 2 is given by:

If we want to know the proportion of the areas, we have:

Thus, the proportion of the areas is:

no problobm
