The answer for the area of the telescope lens in square feet is 0.08507 ft².
The area of the telescope lens is 7903 mm².
We have to convert it from mm² to square feet (ft²).
Therefore, by using the unit conversion factor, we get:
1 feet = 304.8 mm
or, 1 mm = 1/304.8 feet
or, 1 mm = 0.00328084 feet
Squaring both sides, we get,
1 mm² = (0.00328084)²ft²
or, 7903 mm² = (0.00328084)²ft² × 7903 mm² / 1 mm²
= 0.08507 ft² or 8.507 × 10⁻² ft².
Hence, the area of a telescope lens in square feet is 0.08507 ft² or 8.507 × 10⁻² ft².
