Passage:

The adjoining figure is showing '3' stairs if L = 85 cm, B = 45 cm and H = 30 cm.

Based on this information choose the correct option for the question.

Perimeter of side view is

450 cm

In the side view, we have six breadths and six heights to find the perimeter.

Therefore,

Perimeter of side view = 6B + 6H = 6 (B + H) = 6 (45 + 30) = 6 (75) = 450
