$A \,=\, 2lw+\pi(R^2-r^2)$

The area of running track can be expressed in mathematical form and it can be used as a formula in mathematics to find the area of any running track field. It can be derived easily in mathematical form when you understand the geometrical science behind the construction of a running track.

Geometrically, the shape of a running track is the combination of both rectangle and annulus. So, you first have to learn how to find the area of a rectangle and the area of a circular ring.

Now, let’s denote the various dimensions of running track field algebraically as follows.

- Denote the length of straight track lane by a letter $l$.
- Represent the width of straight track lane by a letter $w$.
- Denote the radius of the outer circular lane by a letter $R$.
- Represent the radius of the inner circular lane by a letter $r$.
- Denote the area of running track by a letter $A$.

The area of a running track is equal to the sum of two times the area of rectangular lane and the area of annulus lane.

$A \,=\, 2lw+\pi(R^2-r^2)$
