The length, breadth and height of a room are 9 m, 7 m and 4 m respectively. There are two doors measuring `2m xx 1.5 m` and four windows measuring `1.5m xx 1m`. Find the area doors remaining walls.

Explanation

To find the area of the remaining walls in the room after accounting for the doors and windows, we can follow these steps:

### Step 1: Calculate the area of the four walls of the room.
The room has a length (L) of 9 m, a breadth (B) of 7 m, and a height (H) of 4 m.

The area of the walls can be calculated using the formula:
\[
\text{Area of walls} = 2 \times (L \times H + B \times H)
