The area of a rectangle (A) is:

A = lw --> where l is the length and w is the width

We're given l = 2w, so we substitute this into the Area equation:

A = (2w)w

A = 2w^2

We're given the area of the pitch is 360, so we set:

2w^2 = 360

We type this equation into our search engine, follow the links, and get:

w =

**6*sqrt(5)**

Now we take this, and substitute it into this equation:

6*sqrt(5)l = 360

Dividing each side by 6*sqrt(5), we get:

l =

**60/sqrt(5)**
