Question

formula of triangle
formula of Pentagon​

Answer 1

Answer:

The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.

The area of the Pentagon is equal to 5/2 times the apothem length and of the side of the Pentagon. The formula for the area of the pentagon is 5/2 × s × a. The area of a regular pentagon can similarly be expressed in terms of length of side "s".
