When we study the motion of body then its displacement is described on cartesian plane or in 3d geometry and not in real physical conditions,in this way to calculate the distance travelled by the body is a major aspect in calculating its speed and other things,and here distance formula help us to do so.There are many other importance of distance formula...
If you know the end points then use the distance formula or simply use a ruler.
it is not important
if no geometry in our life, we can't do the other things if we dont have geometry.
Distance = Rate x Time * * * * * Or it could be the area under the speed-time graph. Or, in coordinate geometry, the distance between the points with coordinates (w,x) and (y,z) which is sqrt[(w - y)2 + (x - z)2]. There are analogous formulae for three or more dimensions.
In plane geometry, the shortest distance between two points is a line. In spherical geometry, the shortest distance between two points is a segment of a great circle. The distance between one point and another is known as the displacement.
If you know the end points then use the distance formula or simply use a ruler.
AB = sqrt (x2 - x1)2 + (y2 -y1)2 Sqrt is the square root of
D=(x2-x1)2 + (y2-y1)2then square root the number that you get
Geometry is very important because you practically see it everyday. Everything is geometry. Humans are geometry. planets are geometry. If you don't really understand how much geometry is used and important, then you should try to see somebody for geometry answers.
A formula in geometry is like a formula in other branches of mathematics: it is a mathematical statement that allows you to calculated some measure when given other information.

Mathematicians would say that Renee Descartes, the "Father of Analytical Geometry," is acknowledged as the discoverer of the formula (1596-1650), though there are little write ups on this formula.
to learn more important in geometry
if no geometry in our life, we can't do the other things if we dont have geometry.
Distance = Rate x Time * * * * * Or it could be the area under the speed-time graph. Or, in coordinate geometry, the distance between the points with coordinates (w,x) and (y,z) which is sqrt[(w - y)2 + (x - z)2]. There are analogous formulae for three or more dimensions.
Coordinated geometry was conceived by the French mathematician Rene Descartes.
Because he was the first write a book about Geometry.
