Consider, the garden is in circular shape,
Since, the radius of the semi-circle(or circle) is 42m
and it's perimeter = 2*22/7*r
Therefore, perimeter of the circle = 2*22/7*42=264m
Therefore, the perimeter of the semi-circle = 1/2*perimeter of the circle
Therefore, the perimeter of the semi-circle = 1/2*264
Therefore, the perimeter of the semi-circle = 132m
But, the person jogs 3 times the perimeter
Therefore, the distance jogged by the person = 3*132m = 396m
2 5 2
and it's perimeter = 2*22/7*
sorry for that mistake
