The following are the algorithm to this question:

Explanation:

Following are the steps of the algorithm:

step 1:

To calculate the area of the room, firstly we need to divide the given image into parts and calculate the area of the given image.

step 2:

After calculating each part area, we merge all the parts to calculate the areas.

Calculating area of the parts:

In part 1:

It forms the square shape, and the formula of the square is .   In this diagram we let A=B. that's why the area is .

In part 2:

In this part also forms the square image.  In this, the side is equal to (A-c). so, the area is equal to .

In part 3:

It forms the triangle shape, and the area of the triangle is. the value of "b" is E and the "h" is = (A-C). so, the area is .  

The total area is:
