Question

If the sides of a triangle are 17 cm, 25 cm and 26 cm, find the semi perimeter of the triangle.​

Answer 1

Answer:

34 cm

Step-by-step explanation:

semi perimeter of the triangle =

$\frac{a + b + c}{2}$

a = 17 cm, b = 25 cm, c = 26 cm

semi perimeter of the triangle =

$\frac{17 + 25 + 26}{2}$

=

$\frac{68}{2} = 34$

semi perimeter of the triangle = 34 cm
