Answer:

The total area of the side of the house in the drawing is
$1.4\ in^(2)$

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
(1)/(20)(in)/(ft)

so

$20\ ft=20/20=1\ in$

$24\ ft=24/20=1.2\ in$

$8\ ft=8/20=0.4\ in$

The total area is equal to the area of rectangle plus the area of triangle

so

$A=(1)(1.2)+(1)/(2)(1)(0.4)=1.4\ in^(2)$
