Question

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

Answer 1

Answer:

$12\text{ cans}$

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:

$\text{ Number of Cans = }\frac{2304}{192}\text{ = 12 cans}$
