To calculate the total lineal meters of skirting boards required for the plan, we need to add the perimeter of the walls, while excluding the areas covered by windows and doors. Here's the step-by-step process:

1. Calculate the perimeter of the walls:

For a rectangular space with internal walls, we will first calculate the total length of all walls. The total perimeter of the walls is the sum of the lengths of all the walls.

• Length "A" = 8.529 meters (two walls of this length)
• Width "A" = 5.155 meters (two walls of this width)
• Length "B" = 2.815 meters (two walls of this length)
• Width "B" = 1.623 meters (two walls of this width)

The total length of the walls:

$\text{Perimeter} = 2 \times ( \text{Length "A"} + \text{Width "A"} + \text{Length "B"} + \text{Width "B"} )$

Substituting the values:

$\text{Perimeter} = 2 \times ( 8.529 + 5.155 + 2.815 + 1.623 ) = 2 \times 18.122 = 36.244 \, \text{meters}$

2. Subtract the area of windows and doors:

Now, we'll subtract the areas where the skirting boards won't be required, namely the windows and doors.

• Window "A" has an area of $1.211 \, \text{m} \times 1.740 \, \text{m} = 2.104 \, \text{m}^2$
• Window "B" has an area of $1.307 \, \text{m} \times 0.877 \, \text{m} = 1.146 \, \text{m}^2$
• Doors: There are two doors, each with an area of $2.100 \, \text{m} \times 0.900 \, \text{m} = 1.890 \, \text{m}^2$. So the total area of the doors is $1.890 \times 2 = 3.780 \, \text{m}^2$

However, since skirting boards are typically applied along the edges of walls, we are only concerned with the width of windows and doors for calculation, not their areas. This will give us the lineal distance.

So, the total lineal meters of windows and doors to subtract are:

• Window "A" width = 1.740 meters
• Window "B" width = 0.877 meters
• Doors total width = $2 \times 0.900 = 1.800 \, \text{meters}$

3. Subtract the lineal meters of windows and doors from the perimeter:

Now, subtract the lineal meters of the windows and doors from the total perimeter:

$\text{Total Skirting Length} = \text{Perimeter} - (\text{Window A width} + \text{Window B width} + \text{Doors total width})$

Substituting the values:

$\text{Total Skirting Length} = 36.244 - (1.740 + 0.877 + 1.800)$

$\text{Total Skirting Length} = 36.244 - 4.417 = 31.827 \, \text{meters}$

Final Answer:

The total lineal meters of skirting boards required is 31.827 meters.
