A ladder of 25 ft length reaches a window which is 24 ft above the ground level on one side of the street. Keeping its foot at the same point the ladder is turned the other side of the street and now reaches a window of 7 ft high. then the width of the street?
a] 30 b] 32 c] 29 d] 31

• distance between ladder foot and window base is 25^2=24^2+x^2, so x=7 now distance between ladder foot and opposite side window base is given by 25^2=7^2+y^2, so y=24, then width of the reao is x+y= 24+7= 31.

  25 /7|
  /_ |___
  y x
  by using pythagoras rule we get x=sqrt((25^2)-(24^2))=7
  y=sqrt((25^2)-(7^2))=24
  so width of the road =24+7=31 ft.
