Question

Find the perimeter and semi-perimeter of a triangle whose sides are: 4.6 cm, 5. 3 cm, 6. 4 cm

Answer 1

Answer:

Perimeter = Sum of all three sides

                = 4.6+5.3+6.4

                = 16.3

Semi perimeter = Perimeter/2

                          = 16.3/2

                          = 8.15
