How is the space in a mosque designed to facilitate Muslim prayer and worship?

I dont know anything great about architecture, but I can tell you that Muslims are required to pray in the Direction of Ka’aba (Mecca).
And in a congregation all men stand together to pray in rows, straight lines, one behind the other. This is to promote unity and brotherhod and order. There is an imam who leads the prayer. So keeping this in mind, if you have to design a room you will of course first of all check the direction. The room in order to be straight is often made a little obliquely so that those come to pray have no difficulty.
The have to stand facing the front wall and they are automatically facing the the direction of the Ka’aba. Because this has been taken care of during construction. The engineers design the room facing the Ka’aba.
Hope this helped.
