Correct answer: Explanation: To find the area of any polygon with the side length and the apothem we must know the equation for the area of a polygon which is. First, we must calculate the perimeter using the side length. To find the perimeter of a regular polygon we take the length of each side and multiply it by the number of sides. You could use the sf package to calculate the area of the polygon. First, you have to transform the list of x and y coordinates to a polygon and then calculate its area. library(sf) x_coordinates_1<-c(786.0,712.3,717.7,804.9,866.1,877.5,866.0,823.2,765.5,791.8,830.3,846.9,937.1,941.1,983.2,1020.5,997.1,996.9,921.5,921.2,850.6,850.6,786.0) …Polygon.

Description. a = polyarea (x,y) returns the area of the 2-D polygon defined by the vertices in vectors x and y. If x and y are vectors of the same length, then polyarea returns the scalar area of the polygon defined by x and y. If x and y are matrices of the same size, then polyarea returns a row vector containing the areas of each polygon ... Calculating Area. Find the area of each rectangle from the previous Example. Then, find the ratio of the areas. A s m a l l = 10 ⋅ 16 = 160 u n i t s 2 A l a r g e = 15 ⋅ 24 = 360 u n i t s 2. The ratio of the areas would be 160 360 = 4 9.
