...Mis-read question. The answer is 2 x10^8 m^2. I was two powers of ten out.

It's 200,000 m^2 .....
Can't be, 1 km^2 = 1000000 m^2

so its 200x1000000=200000000

200km^2 is like 200 km x 1km = 200 000m x 1 000m

=> 200 000 000 m^2

It's really not hard, jeese.
5. how many metres are in 1km? now square that numebr and multiply 200 by it. The reason you times by 10,000 for cm is because theres 100 cm in a 1 metre and 100 squared is 10,000
6. 1km2 is the area of a square with sides of length 1km. This is the same as the area of a square with sides of length 1000m, which is 1,000,000m2. So you need to multiply the 200 by 106=1,000,000.
