Question

Word problem involving the area of a rectangle: Problem type 2

Answer 1

`12\text{ cans}`

Step-by-step explanation:

Here, we want to get the number of paint cans needed to paint the room

Firstly, we need to get the area of the ceiling part. Since it is a square, the area is the square of its side length

Mathematically, that would be:

`\begin{gathered} \text{ Area of square = L}^2 \\ \text{where L is side length of square} \\ \text{Area = 48}^2=2304ft^2 \end{gathered}`

Now, to get the number of cans, we have to divide this area by the area in which a can of paint covers

Mathematically, we have that as:

`\text{ Number of Cans = }(2304)/(192)\text{ = 12 cans}`
