type the equation, hit 'ctrl'+'=' for the equal sign, then in the symbolic menu select solve, _ and input the symbolic solve which looks like an arrow. it will look like A = (n*d^2)/4 solve, d ---> answer
There are at least 3 ways to get an answer. All require your area equation with <CTRL>+= instead of =

where the <CTRL>+. is the symbolic evaluation.

In all cases the result will be ±2*sqrt(A/pi), but different versions of Mathcad may have differing approaches to having the sqrt(pi) in the denominator.
