Question

what is the semiperimeter of a triangle whose sides are 2cm ,3cm,5cm .​

Answer 1

Answer:

5 cm

Step-by-step explanation:

perimeter= 2S= (2+3+5)cm

=2S=10cm

So, semi perimeter=( 10/2)cm

=5 cm

Answer 2

Given :-

• A triangle having sides 2 cm, 3 cm and 5 cm.

To Find :-

• The Semi Perimeter of traingle = ?

Answer :-

• The Semi Perimeter of traingle = 5 cm

Explaination :-

As we know that, Semi Perimeter of ∆ is given by formula :

• Semi Perimeter = a + b + c ÷ 2

Where, the sides of ∆ is :

• a = 2 cm

• b = 3 cm

• c = 5 cm

Now, subsitute the value of a, b, c in above given formula :

→ Semi Perimeter = 2 + 3 + 5 ÷ 2

→ Semi Perimeter = 10 ÷ 2

→ Semi Perimeter = 5 cm

Hence,Semi Perimeter of traingle is 5 cm.

Extra Shots :-

• Area of triangle using Heron's formula = √s(s-a)(s-b)(s-c)

• Area of right angled triangle = 1/2 × b × h
