The definition of work is (force) times (distance). If you mean you're given the equation and you need to solve it for 'work', then you only need to multiply both sides of the equation by 'time', and you'll have (power) x (time) = (work)
Power is the change of work over the change of time, ΔW/Δt, or in differential form, dW/dt
