Question

If sides of a triangle are (2a + 4), (4b + 3) and (2c-1) then find the Semi-perimeter of the triangle.​

Answer 1

$\dashrightarrow\bf \: \frac{(2a + 4) + (4b + 3) + (2c - 1)}{2} \\ \bf \to \: \: \frac{2a + 4b + 2c + 4 + 3 - 1}{2} \\ \bf \to \: \frac{2a + 4b + 2c + 6 }{2} \to \: ans.$

Answer 2

Answer:

a+2b+c+3

Step-by-step explanation:

semi perimeter of triangle = a+b+c/2

a=2a+4

b=4b+3

c=2c-1

semi perimeter of triangle=2a+4+4b+3+2c-1/2

=2a+4b+2c+6/2

=2(a+2b+c+3)/2

=a+2b+c+3
