Explanation:

Given : Grant is painting a rectangular board that has a width of 1/3 foot. He has enough paint to cover 3 square feet. If he is able to cover the whole board by using all of his paint.

To find : What is the length of the board in feet?

Solution :

We have given a rectangular board with

Width =
`(1)/(3)` foot

Area paint to cover is A = 3 square feet.

The area of the rectangular is

`A=l* w`

Where, l is the length and w is the width

Substituting the value of w and A

`3=l* (1)/(3)`

`l=3*3`

`l=9`

Therefore, The length of the board is 9 foot.
