The roof of a building is 9 m high. A rope is tied from the roof to a peg on the ground 12 m away from the wall. What is the length of the rope?

15 m

Step-by-step explanation:

Height of buiding h= 9m

Lenght from building l= 12m

let the length of the rope be x=???

Applying Pythagoras theorem

x^2=h^2+l^2

x^2= 9^2+12^2

x^2= 81+144

x^2=225

square both sides

x=√225

x=15 m

Hence the length of the rope is 15 m
