The area A of a rectangular tract of land, is required. Lengths a = 43.678 m, b = 87.355 m and angle a = 30° as shown in the figure, were measured with a 50 m long steel tape and an electronic theodolite with da = 1.75". If the tape is known to be too short by 0.03 m, compute the corresponding error in the calculated area. b a Select one: O a. Corresponding error: 4.88 sq. m. O b. Corresponding error: 4.91 sq. m. O c. Corresponding error: 4.97 sq. m. O d. Corresponding error: 3.94 sq. m.
