If it doubles every 4 hours, in 12 hours you will have 3 doublings.
2 * 2 * 2 = 8
90*8 = 720 pounds of algae

Let breadth be x

Length=x+4

We know

$\boxed{\sf Area_{(Rectangle)}=Length\times Breadth}$

$\\ \sf\longmapsto x(x+4)=22$

$\\ \sf\longmapsto x^2+4x=22$

$\\ \sf\longmapsto x^2+4x-22=0$

By solving

$\\ \sf\longmapsto x=-2\pm\sqrt{26}$
