Question 1059066: The length of a rectangle is 3 times its width. The area is less than or equal to 70 square cm. What is the greatest possible width Answer by jorel555(1290) (Show Source):
You can put this solution on YOUR website! Let w be the width. Then the length is 3w. So:
w(3w)=70
3w²=70
w=±√70/3
l=±3√70/3
The greatest possible width is √(70/3).☺☺☺☺
