Question

If s is the semi-perimeter of a △ABC whose sides are a, b, c, then s =

(a) a + b + c
(b) (a+b+c)/2
(c) (a+b+c)/3
(d)3(a+b+c)​

Answer 1

Answer:

a + b + c divided by 2 is the correct answer

Answer 2

Step-by-step explanation:

semiperimeter of a triangle is given as half of the perimeter which means half of the sum of the lengths of all three sides

Hence, in given question △ABC

semiperimeter =s=

2

a+b+c
