Question

The sides of triangle measure 8cm, 14cm & 8cm, then the semi-perimeter of the triangle is ______ cm. (a) 15 (b) 30 (c) 25​

Answer 1

Answer:

(a) 15

Step-by-step explanation:

Semi Perimeter  $s=\frac{a+b+c}{2}$

where a = 8cm ; b = 14cm & c = 8cm

=> $s= \frac{8+8+14}{2} = \frac{30}{2}$

=> s =15cm
