Divide the pentagon into 5 equal triangles, each with an outermost side length of 182/5 or 36.4 you also know the height of all these triangles will be the length of the apothem, or 25.1 so that you can find the area of a triangle using A= 1/2 bh this gives 456.82, then multiply by 5 to include all of the 5 triangles on the pentagon this gives 2284.1 mm^2 and that is your answer.i hope my response has come to her for help.
