Area and perimeter of triangle and quadrilateral formula in bangla

Answer 1

ANSWER:-

Sorry, I don't know Bengali...but, I can surely help you with it in English.

★ AREAS:-

↪ Triangle- 1/2 × b × h

where b and h are the base and height of the triangle respectively.

or

√s ( s - a) (s - b) (s - c)

where s is the semi perimeter of the triangle and a, b, c are the sides of the triangle.

Also, s = a + b + c/2

↪ Quadrilateral-

b × h.

★ PERIMETER:-

↪ Triangle -

P = a + b + c.

↪ Quadrilateral-

P = a + b + c + d.
