Like the question on this http://getrevising.co.uk/forums/topics/rearranging_equations_another

you follow the same steps..

so your equation is square root of (C+D) = L

1. First square the whole equation

  so you get, c + d = L squared

2. then you take away d from the equation

    so you get c = (l squared) -  d

Hope that helps !!!!!!

Square both sides C+D=L^2

Minus D from both sides C=L^2-D   (
