Question

What is the semi-perimeter of the triangle whose sides are 'a', 'b' and 'c' units respectively?

Answer 1

a+b+c

2

Step-by-step explanation:

semi perimeter = a+b+c

2

By using Heron's Formula :

√ s (s-a) (s-b) (s-c)

you can find the area

If the sides are equal :

a = b = c

Semi perimeter : a+a+a

2

= 3a

The area is :)

√3a (3a - a) (3a - a) (3a - a)

2. 2. 2 2

√3a [(3a - 2a) (3a - 2a) (3a - 2a)

2. 2. 2. 2

√3a (a) (a) (a)

2. 2. 2. 2

√3 a²
