Answer:
463.52 meters
Explanation:
To find the length of the training track running around the field, we need to calculate the perimeter of the entire field.
The field is made up of a rectangle with dimensions 85m by 57m, and two semicircles with a radius of 57/2 = 28.5m.
The perimeter of the rectangle is 2(85m) + 2(57m) = 284m.
The perimeter of each semicircle is half the circumference of a full circle with radius 28.5m, which is π(28.5m) = 89.76m. So the total perimeter of both semicircles is 2(89.76m) = 179.52m.
Therefore, the total perimeter of the field is 284m + 179.52m = 463.52m.
Rounding to the nearest hundredth, the length of the training track running around the field is 463.52 meters.
