Uncle Li used 22 fences with a length of 1 m to form a rectangular sheepfold. How many different ways are there? What is the best way to form a sheepfold?

mathematics

Firstly, 22 fences with a length of 1 m are used to form a rectangular sheepfold, so the circumference of the rectangle is 22 meters, and the sum of its length and width is: 22÷2= 1 1 m. Because the length and width are integers, it is only necessary to satisfy the integer sum of 1 1, so: 1658.

22× 1 ÷ 2 = 1 1m

1 1= 1+ 10=2+9=3+8=4+7=5+6

5×6=30 square meters

A * * * There are five different enclosure methods, and the maximum enclosure area is 30 square meters.
