**For Equilateral Triangles**

- Consider an equilateral triangle of side 3 cm.

Area= ((sqrt 3)/4) * sq. of side.

Area= (1.732/4) * 9

Area= 3.897 sq.cm.

**For Isosceles Triangle**

- Consider an isosceles triangle of side AB=2 cm, BC=2 cm, AC=4 cm. Let ‘AB’ be base (b) and ‘BC’ be height (h).

Area= (base * height)/2

Area= (2 * 2)/2

Area= 2 sq.cm.

**For Scalene Triangles**

- Consider a scalene triangle of side AB=2 cm (a), BC=3 cm (b), AC=4 cm (c).

S= (a+b+c)/2

Area= sqrt (s (s-a) (s-b) (s-c))

Area= sqrt (4.5 (4.5-2) (4.5-3) (4.5-4))

Area= sqrt (4.5 * 2.5 * 1.5* 0.5)

Area= 2.904 sq.cm.

I hope that you understand how to calculate the area of any type of triangles. Please express your opinions.
