a 1kW laser is focused down to 1 cm^ 2 and runs for 10s. What is the energy delivered over time? a. 10 kJ b. 1x10^7 kJ c. 10000 kJ d. 1x10^6 kJ

I've searched for this answer, but no one addresses the part where the laser is being focused down into 1cm^2.. So I'm not sure if that matters or not? Just trying to understand the question.
