the length and breadth of the room were measured and area calculated as 600sq.m. (l+B=50) later found the meter rod that had used as an error 5cm i.e actual length of the rod ws 95cm instead of 100cm. find the correct area of the room

The room was measured to be 20 by 30 m.

So, just multiply each dimension by 0.95 to find the true area.

Or, just do it in one step: 600 * 0.95^2
