we have to apply the theorem of Pitagora, since we have to find x first: |dw:1438810318347:dw| the requested length is: x+a+b

kk

8. Michele_Laino

9. ali2x2

11. Michele_Laino

please can you explain us your procedure step by step @ali2x2 ?

You have a right triangle. The legs measure 4 km. The hypotenuse, c, measures: $$c = \sqrt{a^2 + b^2}$$ where both a and b are 4 km. Then you need to add the length of the hypotenuse to 4 km plus another 4 km. Your answer is correct.
