m BQ=0.7m CQ=2.4m We need to find length AP. Formula used: Distance from the corner point =√(x2+y2+h2) Where, x=0.7m,y=2.4m, and h= height of the lamp =

m.
We can see AQ2=BQ2+AB2 and AB=CQ (Shown in fig.) AP2=AQ2+PQ2 AP2=BQ2+AB2+PQ2 AP=√BQ2+AB2+PQ2 The distance of the top of the lamp from the corner point (AP) is: ⇒ Distance =√(0.72+2.42+(
