<result>D</result>
area of four walls of a room is 99 m 2. the length and breadth of the room are 7.5 m and 3.5 m respectively. the height of the room is:
divide(99, add(multiply(7.5, const_2), multiply(3.5, const_2)))
2 ( 7.5 + 3.5 ) × h = 99 2 ( 11 ) h = 99 22 h = 99 h = 99 / 22 = 9 / 2 = 4.5 m answer is d .
