Correct Answer: 5 km


Solution : Firstly, we will draw the diagram as per the given instructions –

Now, we have to find the shortest distance between home (A) to office (E).


The shortest distance between E to A by using Pythagoras' theorem –
EA 2 = DE 2 + DA 2
EA 2 = 4 2 + 3 2
EA 2 = 16 + 9
EA = 5

Therefore, the shortest distance between home to office is 5 km. Hence, the first option is correct.
