Question

1. which of the following measurements is the best approximation of 1,982 square centimeters? 307 in² 865 in² 7,463 in² 12,787 in²

Explanation:

Step1: Recall conversion factor

1 inch = 2.54 cm, so $1\ \text{in}^2 = (2.54)^2\ \text{cm}^2 = 6.4516\ \text{cm}^2$

Step2: Convert cm² to in²

Divide the given area by the conversion factor:
$\frac{1982}{6.4516}$

Step3: Calculate the value

$\frac{1982}{6.4516} \approx 307$

Answer:

A. $307\ \text{in}^2$
