To find the total amount of time it will take Charla to complete the entire picture, we need to first find the amount of time it took her to complete 2/3 of the area.
If 2/3 of the area is completed in 1/2 hour, then 1/3 of the area will be completed in 1/2 hour as well.
Therefore, it will take Charla 1/2 hour to complete 1/3 of the area.
Since 1/3 + 1/3 + 1/3 = 1, it will take her a total of 1/2 + 1/2 + 1/2 = 3/2 of an hour to complete the entire picture.
Charla wants to cover a certain rectangular area of her driveway with a picture using chalk. If she completes 2/3 of the area in 1/2 hour, how long will it take her to complete the entire picture?(1 point) _of an hour
