A square shaped section of farmland that is 20 feet wide needs to be enclosed by a fence. Additional fencing needs to be installed along the diagonal of the square to separate some of the animals. How much total fencing is needed?

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
