Question

The sides of a triangle measure 20cm 24cm 32 cm then find its semiperimeter

Answer 1

Answer:

let us suppose that a= 20cm b=24cm c=32cm

semi-perimeter = a+b+c/2

                          = 20+24+32/2

                           = 76/2

                           = 38cm

Answer 2

Answer:

Semi-Perimeter = 38 cm.

Step-by-step explanation:

Semi-Perimeter = Perimeter/2

Now,

Perimeter = Sum of sides of the triangle

So,

Perimeter of the triangle = 20 + 24 + 32 = 76 cm

Then,

Semi-Perimeter = 76/2

Semi-Perimeter = 38 cm.
