Given:
Oval track isa combination of a rectangle and circle.
Rectangle: 84 meters by 73 meters
Circle: diameter 73meters

Area of rectangle = 84m * 73 m = 6132 sq.m

Area of a circle = 3.14 * (36.5m)² = 3.14 * 1332.25 m² = 4183.265 sq.m

6132 sq.m + 4183.265 sq.m = 10,315.265sq.m

10,315.265/40 = 257.88 or 258 kilos of seeds needed to cover sa oval.
