Question

If the sides of triangle are 15 , 16 ,18 find the semi perimeter ot the triangle

Answer 1

Answer:

perimeter = a + b + c

                = 15 + 16 + 18

               = 49

semi perimeter = a + b + c / 2

                         = 49 / 2

                         = 24.5 m / cm (not mentioned)

Answer 2
