The perimeter of a circular flower bed is 50.24 meters. There are three kinds of flowers in the flower bed. The planting area of peony accounts for about 1 / 5 of the total area, and the planting area of lily is the same as that of peony Like peony, the rest grow roses. What's the planting area of roses?

Radius 50.24 △ 3.14 △ 2 = 8M
Area: 3.14 × 8 × 8 = 200.96 square meters
So the rose is 200.96 × (1-1 / 5-1 / 5) = 120.576 square meters
