How to take a screenshot of a part of the Yandex map at the right scale?

Question

Yandex maps

I went to Yandex maps, chose the desired area on the scale that I need, but the trouble is that the entire area I need does not fit on my monitor, but only a twentieth part fits. I tried to screenshot in parts, and in paint to connect all these parts, but it's tedious, and sometimes it doesn't fit, I don't know for what reasons, is there some simpler way?
