Jamaat Salaah and Imaamat

Are Ladies Permitted to stand in the saffs of the men in Jamaat Salaah?

Q: Are ladies permitted to stand in the saffs of the men in jamaat salaah. In Bahisti Zewar under the section "Prerequisites of Salaah" there is a masalah that says that the Imaam must make niyyat for a woman who intends joining the Jamaat Salaah if she is standing in line with the men. However if she is standing behind them, then the Imaam does not have to make niyyat for her. This masalah seems to show permissibility for the women to be in line with the men?

Missing the Jammat Despite making the Effort

Q:  I thought that asar jamaat at a certain musjid is 5 pm. when I reached there namaaz was over as jamaat was at 4:45pm. Will I get the reward as if I read namaaz with jamaat? once I saw that jamaat namaaz was over I went inside the musjid and read my own namaaz, even though if I drove 5 minutes away I would have got another jamaat but I didn’t do that as that would have took up my time. Will I still get the reward of namaaz with jamaat even though I could have made it to catch the jamaat somewhere else?
