Now, the area of a triangle is half of the base times height, so: Area of one triangle = base Ã height / 2 = side Ã apothem / 2. To get the area of the whole polygon, just add up the areas of all the little triangles (n of them): Area of Polygon = n Ã side Ã apothem / 2. And since the perimeter is all the sides = n Ã side, we get: Area of Polygon = perimeter Ã apothem / 2.
Intense interest if your cat is focusing on something, like a bird outside, or if heâs about to pounce on a toy (prey). Ecstasy if your cat is really enjoying a grooming session. Anger if the tail is thumping loudly on the floor. An invitation to another cat to play.
