• B. $6300$
• C. $6800$

Answer 1

The correct option is A $6500$

For estimation of $132\times 45$ to the nearest tens place.
We can estimate $132$ to $130$ and $45$ to $50$ as shown:

So, $132\times 45\approx 130\times 50$
$\Rightarrow 132\times 45\approx 13\times 5\times 100$
Now, we can calculate $13\times 5=65$
$\Rightarrow 132\times 45\approx 65\times 100$
$\Rightarrow 132\times 45\approx 6500$
