Question

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 while board by using all of his paint, what is the length of the board in feet.

Answer 1

Length of the rectangular board=9 foot

Explanation:

Width of the rectangular board=1/3 foot

Length of the rectangular board=x

Area of the rectangular board=3 square feet

Area of a rectangular board =Length × Width

3=x * 1/3

3=1/3x

Divide both sides by 1/3

3÷1/3=x

3*3/1 = x

9=x

x=9 feet

Therefore,

Length of the rectangular board= x = 9 foot
