Introduction

When it comes to building or renovating a room, understanding the dimensions of the walls, door frames, and windows is crucial for planning and execution. In this article, we will delve into the world of mathematics and explore how to calculate the dimensions of a wall with a door frame and a window.

Understanding the Problem

Let's consider a wall with the following dimensions:

  • Length (L): 10 meters
  • Width (W): 10 meters

The wall has a door frame with the following dimensions:

  • Door length (DL): 3 meters
  • Door width (DW): 2 meters

Additionally, the wall has a window with the following dimensions:

  • Window length (WL): 3/2 meters (or 1.5 meters)
  • Window width (WW): 2 meters
  • Window height (WH): 1 meter

Calculating the Area of the Wall

To calculate the area of the wall, we can use the formula:

Area = Length × Width

Substituting the values, we get:

Area = 10 meters × 10 meters Area = 100 square meters

Calculating the Area of the Door Frame

To calculate the area of the door frame, we can use the formula:

Area = Length × Width

Substituting the values, we get:

Area = 3 meters × 2 meters Area = 6 square meters

Calculating the Area of the Window

To calculate the area of the window, we can use the formula:

Area = Length × Width

Substituting the values, we get:

Area = 1.5 meters × 2 meters Area = 3 square meters

However, since the window has a height of 1 meter, we need to calculate the area of the window in terms of its length, width, and height. We can use the formula:

Area = Length × Width × Height

Substituting the values, we get:

Area = 1.5 meters × 2 meters × 1 meter Area = 3 cubic meters

Calculating the Net Area of the Wall

To calculate the net area of the wall, we need to subtract the area of the door frame and the window from the total area of the wall. We can use the formula:

Net Area = Total Area - (Door Area + Window Area)

Substituting the values, we get:

Net Area = 100 square meters - (6 square meters + 3 cubic meters)

However, since the window area is given in cubic meters, we need to convert it to square meters by multiplying it by the height of the wall (10 meters). We get:

Window Area (in square meters) = 3 cubic meters × 10 meters Window Area (in square meters) = 30 square meters

Now, we can substitute the values into the formula:

Net Area = 100 square meters - (6 square meters + 30 square meters) Net Area = 100 square meters - 36 square meters Net Area = 64 square meters

Conclusion

In this article, we have explored how to calculate the dimensions of a wall with a door frame and a window. We have used mathematical formulas to calculate the area of the wall, the door frame, and the window, and then subtracted the area of the door frame and the window from the total area of the wall to get the net area. This calculation is essential for planning and execution of building or renovation projects.
