Answer 1

Answer:

firstly it depends upon the type of triangle but if you want to know a formula that can be used to find area of all types of triangle is herons formula.

perimeter = a+b+c

semiperimeter = a+b+c/2

area of triangle =

underroot s-a× s- b× s- c

Answer 2

Question:-

Formula to find Area of triangle

Solution:-

1)If lengths of base and height are given,

Then, area of triangle

$= \frac{1}{2} \times base \times height$

2)If lengths of sides are given

$s = a + b + c$ where a,b and c are sides

Area of triangle

$= \sqrt{s(s - a)(s - b)(s - c)}$
