Explanation:

Use the mirror formula to find the image distance

u = -20 cm
f = -30 cm

# 1/f = 1/u + 1/v#

# 1/-30 = 1/-20 + 1/v#

# -1/30 = -1/20 + 1/v#

# -1/30 + 1/20 = 1/v#

# (-2 + 3)/60 = 1/v#

# 1/60 = 1/v#

# 60 cm = v #

Thus, the image is formed on the right side of the mirror at the distance of 60 cm from the mirror.
