Calculate Area of triangle

Select an option from below options in accordance to the data you have

If you have base and height

If you have length of 3 sides

If you have length of two sides and an angle

base= height=

Area will be calculated here-

Area=

Formula = 1/2*base*height

NOTE: The sum of third side must be less than the other two sides.

a= b= c=

Enter valid side lengths such that each side length should be less than sum of other two sides

Area will be calculated here-

Area=

Formula = √s(s-a)(s-b)(s-c); where s=(a+b+c)/2

b= c= ∠A(deg)=

Area will be calculated here-

Area=

Formula = 1/2*a*b*sin(α)
