The main reason is to get better results.

In optical telescopes, this gives you more resolution. It's similar to having two eyes instead of one...or three or four eyes.
Look at an object and close one eye. You have a slightly smaller field of view and collect less information about it. Looking at it with two eyes which are spaced allows you to see more of the object and gather information about it from two points.
In radio telescopes an equivalent reason exists...basically to gather more infromation about the object. You can read more on it here:

Y don't combined all the antennas . U use two or more groups of antennas and the greater the distance between the group antennas. The greater the triangle base the more accuracy .

The correct answer is that it provides higher resolving power(higher resolution).
