The area of any regular polygon is given by the formula: Area = (a x p)/2, where a is the length of the apothem and p is the perimeter of the polygon. 4. Plug the values of a and p in the formula and get the area. As an example, let's use a hexagon (6 sides) with a side ( s) length of 10.
WebTherefore, the area of a decagon is given as, area of a decagon = area of 10. Web number of triangles in a decagon =.^(10)c(3)=120.how many triangles can be formed in a decagon ? Web a decagon has ten sides, a quadrilateral has four, an octagon has eight, and a triangle has three. Web Thus, The Number Of Diagonals In A Decagon Is 35. WebAnd then using that to calculate the perimeter of the decagon. So we’re going to need our area formula. So let’s recall that from the previous work. So there it is. Area is 𝑛𝑥 squared over four multiplied by cot 180 over 𝑛. Now we know that 𝑛 is equal to 10 because we’re working with a decagon.
