Given Linda is adding the padding to all the surface over the attic
The approximate surface area of the attic including walls floors and ceilings the attic is 4650 [tex](ft)^{2}[/tex]
As shown in figure The Total Surface area of the Attic = Areas of All the Rectangles + Area of both the Triangles shown
[tex]\rm Area\; of\; a\; rectangle\; with \; lenght l \; and\; width \;w = l\times w ,.........(1) \\Area\; of \; a \; triangle\; with \; base\; b\; and \; height \; h = (1/2) \times b\times\ h ,.........(2)[/tex]
All the dimensions are in ft
As there are three rectangles of Size
1. 45 [tex]\times[/tex] 40
2. 25 [tex]\times[/tex] 45
3. 25 [tex]\times[/tex] 45
Also there are two triangles with base 40 and height 15
So the Total Surface area of the attic =
45 [tex]\times[/tex] 40 + 25 [tex]\times[/tex] 45+ 25 [tex]\times[/tex] 45 + (1/2) [tex]\times[/tex]15 [tex]\times[/tex] 40 + (1/2) [tex]\times[/tex]15 [tex]\times[/tex] 40
= 4650 [tex](ft)^{2}[/tex]
