An area was measured to be 1810mm^2 What is this same area in in^2 Note that 1in=25.4 mm. 93.5in^2 2.81in^2 72.3in^2 46,000in^2

To convert the area from square millimeters to square inches, we need to use the conversion factor between millimeters and inches. Given that 1 inch is equal to 25.4 millimeters, we can find the conversion factor for square units by squaring this value.<br /><br />The conversion factor is:<br />\[ (25.4 \, \text{mm/in})^2 = 645.16 \, \text{mm}^2/\text{in}^2 \]<br /><br />Now, we can convert the given area from square millimeters to square inches:<br />\[ 1810 \, \text{mm}^2 \times \frac{1 \, \text{in}^2}{645.16 \, \text{mm}^2} \approx 2.81 \, \text{in}^2 \]<br /><br />Therefore, the correct answer is:<br />\[ 2.81 \, \text{in}^2 \]
