Convert a surface area of 4.7 km^2 to m^2.

4.7km^2 * (1000m)^2
————
1km^2

(1000000m^2)
4.7km^2 * ———————
1 km^2

(4.7km^2)(1000000m^2)
————————————
(1km^2)

(4.7)(1000000m^2)

= 4700000 m^2
= 4.7 x 10^6 m^2

Feel free to comment if you don’t understand my solution.

A) acceleration. this seems to be the one that makes sense.
