Each step of a staircase is 0.25 meter wide and 0.20 meter high, as shown in the figure above. All angles shown in the figure are right angles. If the height of the staircase is 3.6 meters and the landing at the top of the staircase is 1 meter wide, how long, in meters, is AB?
(A) 3.0
(B) 4.25
(C) 4.5
(D) 5.25
(E) 5.5
So if height = 3.6 m this means that there are in total of 18 such steps, each 0.20 m high
Out of which 2 are consumed as shown in the figure remaining will be 16
We are given length of AB in answer choices, we can subtract 1.25 from it, to get the value which, we have to look out for when
answer options / by 0.25 will give us 16
Only D is the correct choice here.
