If the sides of a triangle are a, b and c. Then, what is the semi perimeter of the triangle?
(a+b+c)/2
(a+b+c)
(a+b+c)/4
a+b+c3
If the sides of a triangle are a, b and c. Then the semi perimeter of the triangle = a+b+c2.
If a,b,c are three sides of the triangle, then the perimeter of the triangle is
The area of a triangle, with sides a, b, c and semi-perimeter s, is:
