Generally speaking, the runways of central primary schools are mostly 200m long, but 200m runways: the inner diameter of the curve 16.7m, the straight length is 47.56m, and there are ***4 lanes. The maximum lane width is 1.25m (minimum is 1.22m), and the safe open space is 2m. All lanes should be the same width.

1. radius 16.7m, straight line section 47.56m, width of six runways 7.5m (calculated by 1.25m), and safe open space 2m.

Then: the length needs to be 47.56+16.7+16.7+7.5+7.5+2+2 ≈100m.

The width needs16.7+16.7+7.5+7.5+2+2 ≈ 52m.

The area is100× 52 = 5200m2.

In other words, to build a 200-meter (including 6 runways) standard playground, it needs at least 5,200 square meters. That is, the school playground is about (100) meters long and (52) meters wide, covering an area of (5,200) square meters.

2. Take the radius of 16.7m, the straight section of 47.56m, the width of six runways of 7.32m (calculated by 1.22m), and ignore the safe open space of 2m.

Then: the length needs to be 47.56+16.7+16.7+7.32+7.32 ≈ 96 meters.

Width needs16.7+16.7+7.32+7.32 ≈ 48m.

The area is 96×48=4608 square meters.

In other words, it takes at least 4608 square meters to build a 200-meter (including 6 runways) standard playground. That is, the playground of this school is about (96) meters long and (48) meters wide, covering an area of (4,608) square meters.

Therefore, the school playground area is about 4608 square meters to 5200 square meters.
