Uncle Zhang surrounded a chicken coop by the wall. What is the area of this henhouse? It is 28 meters long and 17 meters wide. If it's near this henhouse,

The area is 17×28=476 (square meters).

According to the picture, there is a wall on the right, so there is no need to build a wall. Therefore, the length of the wall to be built is 28+ 17+28=73 (m).

The cost per meter of fence is about 78 yuan.

The amount of money needed is 73×78=5694 yuan.
