Let's say Stacey starts at point (0,0)

 

She walks 11 meters west to (-11,0)

 

She walks 30 meters north to (-11,30)

 

She walks 4 meters west to (-15, 30)

 

Finally she walks 22 meters south to (-15, 8)

 

she is

 

 \(d = \sqrt{(-15)^2 + (8)^2} = \sqrt{225 + 64} = \sqrt{289} = 17 \text{ meters from her starting point}\)
