Question

If 1 km = 1000 m , then $1m^2=$ $k{m}^2.$

• A. 100
• B. 1000
• C. $\frac{1}{100}$
• D. $\frac{1}{1000000}$

Answer 1

Answer: (B), (D)

$\frac{1}{1000000}$

1 kilometre = 1000 metre
Dividing both the sides by 1000 we get,
$\frac{1}{1000}$ kilometre = $\frac{1000}{1000}$ metre
$\therefore$ 1 metre = $\frac{1}{1000}$ kilometre.

$\therefore 1m^2=\frac{1}{1000}\times \frac{1}{1000}$
$=\frac{1}{1000000}k{m}^2$
