Homework Statement



Einstein's theory of general relativity is relativistic model of gravity. "Relativistic" means it involves the speed of light, c; "gravity" means it involves Newton's constant, G. Use dimensional analysis to derive a formula for the surface area, A, of a black hole of mass M, up to a dimensionless proportionality constant.

Not sure I follow the question.
The only meaningful surface area I can think of for a blackhole is the area of a sphere with the Schwarschild radius.
