A girl walks 200m towards East and then 150m towards North. The distance of the girl from the starting point is

(a)350m

(b) 250m

(c) 300m

(d) 225m

(b) 250m

Explanation:

This forms is a triangle

By Pythagoras theorem

`("Required Distance")^{2}` = `"200"^{2}` + `"150"^{2}`

`("Required Distance")^{2}` = 40,000 + 22,500

`("Required Distance")^{2}` = 62,500

`("Required Distance")^{2}` = `"250"^{2}`

∴ Required Distance = 250 km
