Question

a height of window on second floor of your house is 12 feet high to clean the window from outside you need to put the ladder a feet away to avoid bushes . How long of your ladder do you need in order

Answer 1

If we make a triangle than the ladder becomes the hypotenuse and the ground becomes the base so by using Pythagoras theorem
Ladder^2= base^2+ window^2
Ladder^2 =1^2+12^2
Ladder^2=1+144
Ladder=root 145
