Question

Area of four walls of a room is 48 m² and size of a door is 2m by 5m and there are two windows of size 2m by 2m then what is area of four walls excluding door and window?

Answer 1

To find the area of the four walls excluding the door and windows, we first need to calculate the total area of the door and windows and then subtract it from the total area of the four walls.

1. Calculate the area of the door: The size of the door is 2m by 5m, so the area of the door is: Area of the door = Length × Width = 2m × 5m = 10m²

2. Calculate the area of both windows: The size of each window is 2m by 2m, and there are two windows, so the total area of both windows is: Area of both windows = 2 × (2m × 2m) = 2 × 4m² = 8m²

3. Calculate the total area of the four walls: Given that the total area of the four walls is 48m².

4. Subtract the area of the door and windows from the total area of the four walls to find the area of the four walls excluding the door and windows: Area of four walls excluding door and window = Total area of four walls - Area of the door - Area of both windows

Area of four walls excluding door and window = 48m² - 10m² - 8m² = 30m²

So, the area of the four walls excluding the door and windows is 30 square meters.
