(Solved) : 10 Computation Areas Consider Figure 1 1 Shows Tract Land Subdivided Triangles Computation Q32903192 . . .
Can some one solve this please it is surveying class civilengineering1.0 COMPUTATION OF AREAS Consider Figure 1-1 which shows a tract of land which has been subdivided into triangles. computation of the area, A, of each triangle can be obtained using the following formula The A [s(s-a)(s-bs-c)I/2 where a.b, and c are the lengths of each side of a triangle and s (1/2a+b+c). (1-2) Another formula is given by A = (l/2) ab sin C (1-3) where C is the angle included between the sides a and b. For the special case where C 90 degrees, the area is given by A (1/2) ab. (1-4) 1.2 Area by Offsets From Straight Lines 1.2.1 Offsets at Regularly Spaced Intervals Consider Figure 1-2 which shows a reference line and the offsets from the reference line. For the case of regularly spaced offsets, the area can be computed by (1-5) where b is the length of the common interval between offsets and h, hi, h…., h, are the offsets. For the data given in the figure the area can be computed to be 2,860 ft 1.2.2 Offsets at Irregularly Spaced Intervals Consider Figure 1-3 which shows a reference line and a curved boundary for which the area needs to be determined. Notice the spacing between the offsets is irregular. The formula for calculating the area with this case is given by (1-6) where a,b.c,… are the varying offset spacings, and h, h, h, h, Figure 1-3, the area can be computed to be 4,490 ft’ are the measured offsets.
