Question

what is the formula to find semi perimeter of the triangle​

Answer 1

Answer:

We recall the dentition of length of sides of a triangle, the perimeter of the triangle and then semi-perimeter. We add the given lengths of triangles to get the perimeter of the triangle and divide the perimeter by 2 to get the semi-perimeter.

Step-by-step explanation:

(Formula of semi perimeter)

In any triangle, the distance along the boundary of the triangle from a vertex to the point on the opposite edge touched by an excircle equals the semiperimeter.

hope it helps you !!!!

Answer 2

Answer:

a+b+c/2

Step-by-step explanation:

let,

a= side 1

b= side 2

c= side 3

perimeter of triangle is a+b+c . so, for find semi perimeter of triangle. these sides is divided by 2. to find semi perimeter get half of perimeter.
