$perimeter of traingle$
​

Answer 1

Answer:

area of triangle = 1/2 × base ×height

perimeter of triangle = sum of all sides

Step-by-step explanation:

i think do u need formula

Answer 2

area of triangle :

i) herons formula : a, b, c, are sides of triangle and S is the semi perimeter(a+b+c/2) of the triangle

so, area of triangle =

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

ii) commonly known formula :where b is base and h is the corresponding height .

so the area = (1/2)bh

perimeter of triangle :

I) a+b+c, where a, b, c, are sides (scalene triangle)

II) 3a, where all side are equal to a (equilateral triangle)

IIII) 2a+b , where 2 side are equal to a and other is b (isoceles triangle)
