I assume there is a tilted rectangle in the figure. If so, then the answer is to your question is yes, it is possible.

I assume you want to know how?

(You should write more specifically.)

Here is one way. Refer to my attachment.

L and H are known, from the coordinates circled in red.

We have similar triangles.

Also,

Substitute

We know that

We can now solve for (discard the value ). From this we can obtain the values of all variables.

When L = 7.5 and H = 8.5, I get .
