The correct answer, from a Muslim, is that we pray separately for reasons of modesty and it is totally possible to get attracted as GOD has created attraction Between Men and Women). In the time of the Prophet Mohammad (pbuh) women would pray in rows behind the rows of men. If they prayed in front of the men or mingled with the men then when we prostrate men would get a direct view of womens bottoms, this is not a way to be modest and would make it difficult for everyone to concentrate on their prayers.
These days we either pray behind the men, in rows adjacent to men, with a curtain dividing men and women or in a separate prayer room for women.
The prayer room is used for offering prayer. It is also used for learning/teaching of the holy Qur'an and sunna. It is also used for delivering lectures on various topics of Islam.
The building for a Muslim prayer is called a Mosque
it's and area that leads into the prayer room that has arches.
Mosque
Not really a mosque as a set aside area for a prayer room is very possible.
It varies from mosque to mosque. It can be as simple as a dirt floor, or as ornate as a carpeted room with bookshelves, fans, and chandeliers. Most mosques are somewhere in the middle, with a simple carpeted floor and a few bookshelves.
Minaret is the part of a mosque that is used to call followers to prayer. Not any more, this was done before loudspeakers were introduced, but now it is done inside the Masjid.
An Imam is the name for a mosque prayer leader.Anybody who leads a congregational prayer (in a mosque or not) is know as the imam.
One example is: a Wudu Room, Prayer Room and Shoe Hall, but there can be many different ways depending on the mosque.Some mosques have only the Prayer Room.
a mosque
Worship at home or work is no different from in a Mosque. The mosque is not a sacred place, it is an agreed place for prayer. Any clean part of a home may be used for prayer.
They wash their hands and feet in a washing room annexed to the mosque.
If it is an entire building, i.e. the Islamic equivalent of a church, it would be called a mosque. If it is a room in a larger structure that has a non-religious purpose, such as in a bus station, hospital, etc., i.e. the Islamic equivalent of a chapel, it is called a musallah. If you are talking about a massive structure, i.e. the Islamic equivalent of a cathedral, that would be a jame'a.
