Question

À certain wall is 13 ft by 9 ft. A can of paint willcover 50ft? Will one paint can be enough?Draw a picture:a

Answer 1

To answer this question, we need to calculate the area of the given wall first to know the area to be painted, and we have the following information:

• We have that the dimensions of the wall are 13ft by 9ft.

,

• A can of paint will cover 50ft² (50 square feet).

Then we have:

1. Find the area of the wall:

$\begin{gathered} A_{wall}=13ft*9ft \\ A_{wall}=117ft^2 \end{gathered}$

2. Therefore, we have that a can of paint can cover only 50ft², then it can paint only:

$\frac{50ft^2}{117ft^2}\approx0.42735042735\approx0.43\text{ \lparen Or about 43\% of the wall\rparen}$

3. Therefore, we can say that the paint can cover about 43% of the wall.

Then we have:

Will one can of paint be enough?

No, one can of paint will not be enough since it can cover, approximately, 43% of the area of the given wall.
