In order to estimate the products, we need to round of the given numbers. For estimating the products, we first round off the multiplier and the multiplicand to the nearest tens, hundreds, or thousands and then multiply the rounded numbers.

Required Answer :-

42 → 40 (42 is rounded down to 30)

127 → 130 (127 is rounded up to 130)

Now,

We will find the product of 40 and 130

$\rm:\implies{40 \times 130}$

$\large{ \boxed{ \underline \color{blue}{ = 5200}}}$
