Answer:

The length of the board is 9 foot.        

Step-by-step 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 = $\frac{1}{3}$ foot

Area paint to cover is A = 3 square feet.

The area of the rectangular is

$A=l\times w$

Where, l is the length and w is the width

Substituting the value of w and A

$3=l\times \frac{1}{3}$

$l=3\times3$

$l=9$

Therefore, The length of the board is 9 foot.
