The number of images formed when two mirrors are inclined to each other is given by :
n=(360/θ -1)
here θ= 90°[since walls are perpendicular]
so, number of images=n=360/90-1
=4-1
=3
These 3 images are formed by combination of two adjacent walls with object itself acts as objects for ceiling mirror. So totally 4 images are formed .
Hence total number of images formed are 4+3= 7
