Question

what is formula of triangle​

Answer 1

Answer:

1/2 base ×height.....

Answer 2

Step-by-step explanation:

area of triangle

= 1/2 X base X height

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

where

$s = \frac{a + b + c}{2}$

area of equilateral triangle =

$\frac{ \sqrt{3} }{4} {a}^{2}$

where A is length of the side of equilateral triangle

perimeter of a triangle

= samadhi lengths of its sides

=AB+ BC + CA

=a+b+ c
