One football field is 300 yards from goal line to goal line. 1 yard = 3 feet. If you are wanting to know how many feet are from goal line to goal line, it would be 300 feet. The end-zones are another 10 yards each. This adds another 60 total feet. If you are asking from goal post to goal post it would be 360 feet.
It depends entirely on the size of the field !
A plane is the set of all points in 3-D space equidistant from two points, A and B. If it will help to see it, the set of all points in a plane that are equidistant from points A and B in the plane will be a line. Extend that thinking off the plane and you'll have another plane perpendicular to the original plane, the one with A and B in it. And the question specified that A and B were in 3-D space. Another way to look at is to look at a line segment between A and B. Find the midpoint of that line segment, and then draw a plane perpendicular to the line segment, specifying that that plane also includes the midpoint of the line segment AB. Same thing. The set of all points that make up that plane will be equidistant from A and B. At the risk of running it into the ground, given a line segment AB, if the line segment is bisected by a plane perpendicular to the line segment, it (the plane) will contain the set of all points equidistant from A and B.
When the line is inclined to the plane. That is, it is not in the plane nor is it parallel to it.
There are three things that are considered undefined terms in geometry. Those are line, point, and plane. A line is something that has no depth, but extends indefinitely. A plane has no depth, but it extend indefinitely in every direction. A point no actual size or dimension.
The goal post dimensions in Canadian football are the same as in American football. The goal posts are on the goal line. The hash marks are not in line with the uprights.
A football is 11 inches long. There are 32 inches in a yard. A football field is 100 yards long from goal line to goal line. Therefore it would take 290 footballs to span from goal line to goal line.
All football fields are 100 yards long from goal line to goal line
100 yards.
100 yards
3600 inches
by kicking the ball in the goal!! the best and original type of football. american football is stupid
On the goal line
the length of a football filed is 100 yards from goal line to goal line
ten yards
It's known as the goal line.
The ball is placed at the 2 yard line in the NFL and the 3 yard line in college football.
