A rectangular yard had a length of 0.006 kilometer and a width of 5x10^-3 kilometers.
A. Use scientific notation to express the ares of the yard in kilometers, showing each step in the process.
B. Convert the area into square meters using the conversion below.
1 sq. kilometer (km^2)=1x10^6 sq. meters (m^2)
Give your answer in standard form. Which unit is a better choice formeasuring the area of the yard and why?

6*10^-3 * 5*10^-3
= 30 * 10^-6
= 3 * 10^-5 km^2
3 * 10^-5 km^2 * 10^6 m^2/km^2
= 3*10^1 = 30 m^2
30 m^2 is a lot easier to visualize than 30 millionths of a km^2
= 30 * 10^-6
= 3 * 10^-5 km^2
3 * 10^-5 km^2 * 10^6 m^2/km^2
= 3*10^1 = 30 m^2
30 m^2 is a lot easier to visualize than 30 millionths of a km^2

THANK YOU, thank you. I am sooo lost. I understand up to 30*10^6. I'm not sure what part is A and what part is B. Please explain in very simple terms. Thanks:-)
