Charla wants to cover a certain rectangular area of her driveway with a picture using Chuck if she completes 2/3 of an area in 1/2 hour how long will it take her to complete the entire picture
If Charla completes 2/3 of an area in 1/2 hour, then we can represent the entire picture as 1.
To complete 2/3 of the area in 1/2 hour, Charla takes 1/2 / (2/3) = 3/2 / 2/3 = 3/2 * 3/2 = 9/4 = 2.25 hours to complete the entire picture. Answer: \boxed{2.25}.
