Question

A bulletin board is 8 feet long. It covers an area of 40 square feet. What is the width of the bulletin board? Show your work.

Answer 1

We will assume that the bulletin board has the shape of a rectangle.

The area of a rectangle is given by the following formula:

$A=l\times w,$

where l is the length of the rectangle and w its width.

Now, we know that the bulletin board has an area of 40 square feet and it is 8 feet long, therefore:

$40ft^2=8ft\times w.$

Solving the above equation for w, we get:

$\frac{40ft^2}{8ft}=w.$

Answer:

$5ft\text{.}$
