SECTION PROPERTIES (Area, Centroid, ...)

This app. determine the properties of polygonal

sections. The (x,y) coordinates of the vertices

of the polygon (which must be located entirely

within the first quadrant) are input sequentially

for a complete clockwise path around the

polygon. Holes in the cross section, which

do not intersect the boundary, may be deleted

by following a counter-clockwise path.

Aplikasi ini. tentukan sifat poligonal

bahagian. Koordinat bucu (x, y)

poligon (yang mesti terletak sepenuhnya

dalam kuadran pertama) dimasukkan secara berurutan

untuk jalan arah jam yang lengkap di sekitar

poligon. Lubang di bahagian rentas, yang

jangan memotong batas, boleh dihapuskan

dengan mengikuti jalan berlawanan arah jam.
