Answer: Option A
:
(i) Formula: 1 Mark
Result: 1 Mark
(ii) Formula: 1 Mark
Result: 1 Mark
(i) Given: The height of the staircase = 6 cms
The breadth of the staircase = 32 cms
So, length of the pink line will be = (breadth + height) of five steps.
⇒5 (6 cms) + 5 (32 cms)
⇒5[6+32] cms
⇒5[38] cms
⇒190 cms
(ii) The total length of the in−stepThe total length of the pink line
⇒5(6) cms190 cms
⇒30190⇒319
