For entirely legal reasons you need to get into an open wind

For entirely legal reasons, you need to get into an open window, which is 20 ft up the side of a building. You have a 24 ft ladder, but due to large bushes around the building, you can\'t get the foot of the ladder closer than 12 ft from the base of the wall. Can you reach the windowsill with your ladder (Draw a picture to help support your argument)

Solution

height of window =20ft

maximum closer distance =12 ft

by pythogorus theorem

length of ladder to be required to reach window = [20²+12²]

length of ladder to be required to reach window = [544]

length of ladder to be required to reach window = 23.32ft

given ladder length =24ft

so required ladder length less than given ladder length so window can be reached by ladder
