Question

BlackTom AI · Accepted Answer

We are asked to find the area of (one megameter) × (one gigameter).
First, recall unit conversions: 1 megameter (Mm) = 10^6 meters, and 1 gigameter (Gm) = 10^9 meters.
Multiplying the lengths gives: (10^6 m) × (10^9 m) = 10^(6+9) m^2 = 10^15 m^2.
Now evaluate the options:
- Option a: 1000000000000000 metre square equals 10^15 m^2. This matches the calculated area, so this option is correct.
- Option b: 10000000000000000000 metre square equals 10^19 m^2. This is too large by a factor of 10^4; it would correspond to (10^7 m) × (10^12 m) or similar, which is not our case.
- Option c: 1000000 metre square equals 10^6 m^2. This is far too small for the product of 10^6 m and 10^9 m.
- Option d: 1000000000000 metre square equals 10^12 m^2. This is also too small compared to the expected 10^15 m^2.
In summary, converting the units properly and multiplying the exponents yields 10^15 m^2, which aligns with option a's value.
