Final answer:
The perimeter of a square is obtained by multiplying the side's length by 4. A square desk's perimeter measured by Priya is 248 cm, meaning each side is 62 cm. Samir's 10-kilometer race is equivalent to running 10,000 meters.
Step-by-step explanation:
To find the perimeter of a square, you multiply the length of one side by 4, as a square has four equal sides. However, for the problem you presented regarding the desk, it seems there is a discrepancy between the measurements provided by Priya and Noah. Assuming Priya's measurement is correct since the perimeter of the square desk is 248 cm, each side of the desk would be 62 cm (since 248 cm ÷ 4 = 62 cm). If Noah's measurement of 2,468 cm is accurate for the perimeter (which is unlikely and possibly a typo), it would mean each side of the desk measures 617 cm. For the measurement discrepancy to be addressed, we need to confirm the actual measurement with the proper tools and techniques. Regarding Samir's race, 10 kilometers is equivalent to 10,000 meters, as there are 1,000 meters in each kilometer. Therefore, Samir ran 10,000 meters.
