### Write in Short

Short Answer▾In a triangle without changing the angle if we double the sides then what will be the new area?

### Explanation

- Area of an equilateral triangle = / 4 L
^{2}, where, L = side of a triangle

A_{old} = L^{2}

- New length = 2L
- So, A
_{new}= (2L)^{2}

= 4 [] L^{2}

= 4

- So, we can say that by doubling the side of a triangle, area of new triangle will be four times the area of previous one.
