Andrew can reach a maximum of high up the wall.
The right-angled triangle formed can be solved using the ratio. that is
where is the distance from the foot of the wall to the tip of the ladder where it rests on the wall. Substituting, and solving for
, we get
Since Andrew can reach an extra above the point where the ladder rests against the wall, the maximum height Andrew can paint is
