Step-by-step explanation:
The choice of vocabulary here is entirely about clarity and lack of ambiguity. Mathematics does not prescribe rules about “proper” use of these terms for that context. In mathematics as elsewhere, the purpose of specialized vocabulary is to serve clear, unambiguous communication. In this case, our natural way of talking gives us some guidelines.
Length: If you choose to use the word length, it should refer to the longest dimension of the rectangle. Think of how you would describe the distance along a road: it is the long distance, the length of the road. (The words along, long, and length are all related.) The distance across the road tells how wide the road is from one side to the other. That is the width of the road. (The words wide and width are related, too.)
When a rectangle is drawn “slanted” on the page, like this, it is usually clearest to label the long side “length” and the other side “width,” as if you were labeling a road.

Height: When a rectangle is drawn with horizontal and vertical sides, the word height makes it clear which dimension is meant; height labels how high (how tall) the rectangle is. That makes it easy to indicate the other dimension—how wide the rectangle is from side to side—by using the word width. And if the side-to-side measurement is greater than the height, calling it the length of the rectangle is also acceptable, as it creates no confusion.
