Question

A scale drawing of the side view of a house is shown at the right. Find the total area (in square inches) of the side of the house in the drawing PLEASE HELP!!

Answer 1

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)`
