Finding the Area of the Brick Wall

To find the area of the brick wall, we need to calculate the area of the triangular part and the rectangular part separately and then add them together.

1. Area of the Triangular Part: - The area of a triangle can be calculated using the formula: Area = (base * height) / 2. - In this case, the base of the triangle is the width of the window, and the height is the height of the wall.

2. Area of the Rectangular Part: - The area of a rectangle can be calculated using the formula: Area = length * width. - In this case, the length of the rectangle is the width of the wall minus the width of the window, and the width is the height of the wall.

Calculation

Let's assume the following measurements: - Width of the window = w units - Height of the wall = h units - Width of the wall = W units

Then, we can calculate the area of the brick wall as follows:

1. Area of the Triangular Part: - Area_triangular = (w * h) / 2

2. Area of the Rectangular Part: - Area_rectangular = (W - w) * h

Total Area of the Brick Wall: - Total_area = Area_triangular + Area_rectangular

Conclusion

By using the given measurements and the formulas for calculating the area of a triangle and a rectangle, we can find the total area of the brick wall.
