Unformatted text preview: 6. (a) Using the fact that the area A of a rectangle is widthlength, we find Atotal = = = (3.00 acre) + (25.0 perch)(4.00 perch) (40 perch)(4 perch) (3.00 acre) + 100 perch2 1 acre 580 perch2 . We multiply this by the perch2 rood conversion factor (1 rood/40 perch2 ) to obtain the answer: Atotal = 14.5 roods. (b) We convert our intermediate result in part (a): Atotal = (580 perch2 ) 16.5 ft 1 perch
2 = 1.58 105 ft2 . Now, we use the feet meters conversion given in Appendix D to obtain Atotal = 1.58 105 ft2 1m 3.281 ft
2 = 1.47 104 m2 . ...
