Answer: Two values are 369600 and 300000.
Step-by-step explanation:
If we rounding the integers to nearest ones ,
\(1537 \text{change into }1540\\\\242\text{ change into }240\\\\So,\\\text{Sum will be }\\=1540\times 240\\=369600\)
If we rounding the integers to nearest tens,
\(1537\text{ changes to }1500\\242\text{ changes to }200\\So,\\\text{Sum will be }\\=1500\times 200\\=300000\)
Hence, by estimation, we get
Two values from above two cases are 369600 and 300000.
