It is not reasonable, because if we estimate by rounding each factor and multiplying the result. It would be higher than 53,253

<h3>Further explanation</h3>

When we estimate a calculation we can rounding each factor. In this case would be:

1,729 rounding to 2000

308 rounding to 300

2000 x 300 = 600,000

which is higher than 53,253. So if we multipy the exact number the result would be higher.

to get the precise result, we can use the area model

$=\boxed {1729 \times308\ }\\ =\boxed{(1000+7000+20+9) \times(300+8)\ }$

$=\boxed{\(300000+210000+6000+2700+8000+5600+160+72)\ }\\ =\boxed {532532\ }$

Nope if you round the first number to 2000 and the second to 300 you should expect around 600000 which is not the case.
