Answer:
The total area of the side of the house in the drawing is [tex]1.4\ in^{2}[/tex]
Step-by-step explanation:
step 1
Convert the actual dimensions of the side view of a house to the dimensions of the drawing
The scale of the drawing is [tex]\frac{1}{20}\frac{in}{ft}[/tex]
so
[tex]20\ ft=20/20=1\ in[/tex]
[tex]24\ ft=24/20=1.2\ in[/tex]
[tex]8\ ft=8/20=0.4\ in[/tex]
The total area is equal to the area of rectangle plus the area of triangle
so
[tex]A=(1)(1.2)+\frac{1}{2}(1)(0.4)=1.4\ in^{2}[/tex]
