A painter ​​leans his back against a painted wall while looking into a 1 meter long mirror at the opposite end of the rectangular room.If the other two walls measure 12 meters.Hoew much of the painted wall can he see in the mirror?
 

Dear Student,

Assume that the painter is facing the centre of the mirror. To see the maximum range, he has to look at the two extreme ends of the mirror. By applying angle of incidence = angle of reflection, the maximum length of painted wall is 2 m.

Regards
