A farmer wants to put a fence around a garden in the shape of a square. The fence posts are placed every 2 meters. One side of the garden is 10m long. How many posts does the farmer need?
If one side of the garden is 10m long, and the garden is a square, we can assume that all 4 sides will be 10m. That makes it 40m in total. Times 40×2 and you get 80.
