And length of room is

Then the old area will be

Also we have to make this room three times larger as it is now.

We can see the ratio between width and length of room is

let us say the length of new room is

So, width of room will be

And we know area of rectangle is

Also, the new area will be

Then the equation will be

So, the width of new room is

So, the increment in width is

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
