Question

You need to go from point A to point B and must walk along the side of the building. Which way is shorter?

Answer 1

Both routes are the same.

That's the answer.

Explanation:

Answer 2

Route 1 is shorter

Explanation:

Route 1:

3 + 10 + 2 = 15 units

Route 2:

3 + 3 + 4 + 4 + 3

= (6) + (8) + (3) = 20 units

Therefore, route 1 is 5 units shorter than route 2.
