Question

The semi-perimeter of a triangle having sides 75 cm, 80 cm and 95 cm is____​

Answer 1

semi-perimeter = sum of sides of triangle / 2

                         = a+b+c/2

                         = 75+80+95/2

                         = 250/2

                         = $125cm^{2}$

hope this helps!

Answer 2

Answer:

125 is the answer...

Perimeter of triangle=a+b+c

=75+80+95

=250

so Perimeter is triangle=250cm

Now, semi-perimeter of triangle=P/2

=250/2

=125 Ans

so semi-perimeter of triangle=125cm
