Answer:

11340

Step-by-step explanation:

Power = Work/time.

P = W/t ................ Equation 1

Make W the subject of the equation,

W = Pt.................. Equation 2

Given: P = 270 Watts, t = 42 seconds

Substitute these values into equation 2

W = 270(42)

W = 11340 J

Hence the work done is 11340
