Let's take a look at the numbers running down the left. They are increasing by how much?

Take a look at the numbers running down the right. They are increasing by how much?

Our carpets continue to have the ratio of 4:3.

Because these two columns (L & W) are increasing by the same rate for each carpet piece, we say they have the same ratio of L to W.

The missing piece has to be 20 by 15 (a ratio of 4:3)

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

it would open into a square depending on the type of envelope i’m not sure about the second part
