A playground runway is a rectangle in the middle, 110 meters long and 50 meters wide. There are six runways, 1.2 meters each. How to find the area

The runway is generally a rectangle + 2 semicircles (in fact, it is a rectangle + 1 circle)
The total area of the playground runway is 110 × (50 + 2 × 6 × 1.2) + π (50 △ 2 + 6 × 1.2) ∧ 2
About 10340 square meters
If you calculate the area of the runway, it is equal to the area of the ring + the runways on both sides, which is also very good
