The lenght of a room exceeds its breadth by 3 meters. If the lenght is increased 3 meters and the breadth is decreased by 2 meters, the area remaings the same. Find the lenght and the breadth of the room.

Answer

length = 15 m, breadth = 12 m

Explanation

Let length = x metres and breadth = y metres
Then, ` x = y + 3 and (x + 3 ) ( y - 2) = x y `.
` therefore x - y = 3 and 3y - 2x = 6`.
