Question

derivation of half perimeter formula from are of triangle formula​

Answer 1

Answer:

For a triangle of given three sides, say a, b, and c, the formula for the area is given by. $A = \sqrt{s(s - a)(s - b)(s - c)}$. where s is the semi perimeter equal to P/2 = (a + b + c)/2. Derivation of Heron's Formula. Area of triangle ABC.

Answer 2

Heya mate!!

area = ( s − a ) ( s − b ) ( s − c ) ( s − d ) . The circumradius R of a triangle can also be calculated from the semiperimeter and side lengths: 2R=D=abc2√s(s−a)(s−b)(s−c). 2 R = D = a b c 2 s ( s − a ) ( s − b ) ( s − c )

Hope it helps u dear ✌️✌️☺️
