Answer 1

Answer:768in

Explanation:

Answer 2

We can divide the street sign in three figures. First, we can make a rectangle with the post:

the area of this rectangle is:

`A_r=(8)(75)=600in^2`

next, with the sign we can make a square and a rectangle like this:

which have the following areas:

`\begin{gathered} A_s=(12)(12)=144in^2 \\ A_t=((12)(4))/(2)=(48)/(2)=24in^2 \end{gathered}`

Now we add all the areas to get the total painted area:

`A=A_r+A_s+A_t=600+144+24=768in^2`

therefore, the painted area is 768 in^2
