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 = [tex]\frac{1}{3}[/tex] foot
Area paint to cover is A = 3 square feet.
The area of the rectangular is
[tex]A=l\times w[/tex]
Where, l is the length and w is the width
Substituting the value of w and A
[tex]3=l\times \frac{1}{3}[/tex]
[tex]l=3\times3[/tex]
[tex]l=9[/tex]
Therefore, The length of the board is 9 foot.
