So, he wittingly set up a theodolite at point A, where angle BAD is exactly 90°, and he used stadia to measure the distance between points A and F, the center of the square lot BCED. The upper and lower hair readings were1.20 m and 0.92 m, respectively. The stadia interval factor (K) is known to be 101.0152545 and the instrument constant (C) is zero. He then set up the same instrument at point A and used a 2-meter subtense bar at point D to find the distance between points A and D. The subtended angle was read as 3°49'5.9". Using the computed distances of AF and AD, what is the area of the square BCED? (Round your final answer to 6 decimal places, if necessary.) The area of the square lot BCED is m?.

and F, the center of the square lot BCED. The upper and lower hair readings were1.20 m and 0.92 m, respectively. The stadia interval factor
(K) is known to be 101.0152545 and the instrument constant (C) is zero.
He then set up the same instrument at point A and used a 2-meter subtense bar at point D to find the distance between points A and D.
The subtended angle was read as 3°49'5.9".
Using the computed distances of AF and AD, what is the area of the square BCED?
