Answer 1

`70`

Step-by-step explanation:

What we want to answer in this question is simply, the area of the room that will be painted blue if he decides he would paint exactly have the room blue

So, we need to simply get the area of the room and divide this by half

Mathematically, the area of a rectangle is the product of its two sides

Thus, we have it that the area of the room is:

`\begin{gathered} 8(2)/(5)*16(2)/(3) \\ (42)/(5)*(50)/(3)\text{ = 14}*10=140ft^2 \end{gathered}`

Now, to get the area painted blue, we divide this by 2 as follows or multiply by 1/2

We have this as:

`140*(1)/(2)=70ft^2`
