The correct answer is 340m
Explanation
the image shows a contour line map. A contour line is a tool used in geography and other areas in which the surface and its represented through lines formed by those points on the ground that are at the same altitude, for example, the thickest line is at 350m and the one that follows it is at 340m of altitude. According to the previous explanation, if it is required to know how high point A is, it is necessary to know how high the line is on which this point is located or to know the altitude of one of the lines following or preceding it. In this case, line A is before the thickest line that is at 350m altitude, therefore the line where point A is located is at 340m altitude.
