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* 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* w.

Solving the above equation for w, we get:


(40ft^2)/(8ft)=w.

Answer:


5ft\text{.}
