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* 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{.}`
