Josh has and extension ladder which is 9.8m long. He needs to clean the windows on the outside of a building. The lower part of these windows is 9.8m from the base of the building, and they are 1.2m tall. Unfortunately, the closest Josh can place his ladder to the base of the building is 3m, as there are bushes preventing him from putting it any closer. Josh is 1.2m tall.
