Hey i'm having a hard time with the following question.(adsbygoogle = window.adsbygoogle || []).push({});

This problem appears deceptively simple, but the challenge is to obtain three independent equations inx,y,zthat can be solved to determine the areas of the regions.

A square has sides 6 cm long. Four quarter circles are inscribed in the square. Determine the areas of the three different kinds of regions that are formed.

I am only missing the 3rd equations.

The two that I found are:

-> 4x+4y+z = 36

-> 2x+3y+z = 9pi

After many hours of trial and error i can find the third equation.
