### Question

#### In a Δabc if b+c=3a then has the value equal to –

- 4
- 3
- 2
- 1

### Hint:

**Semi perimeter of triangle = Sum of all sides, also**

#### The correct answer is: 2

#### Given :In a Δabc

b + c = 3a

Adding a on both sides

a + b + c = 4a

We know that Semi Perimeter of triangle(2S) = a +b + c

2s = 4a

s = 2a
