Answer:

11:40

Step-by-step explanation:

You can do 60-20 which is 40. Since you know there are 60 minutes in a hour, and you need 20 minutes earlier, you can subtract those which give you 40. Add 11 before it because you want to find 20 minutes earlier, which gives you 11:40.

The perimeter of a rectangular garden is 346. if the width of the garden is 79 feet, what is its length?
