Area Of Equilateral Triangle Formula The area of an equilateral triangle is the region occupied by it in a two dimensional plane The formula for the area of an equiangular triangle is given by A 3a2 4 Let us derive the formula here If we see the above figure the area of a triangle is given by Area 189 x base x height
As the name suggests equi means Equal an equilateral triangle is the one where all sides are equal and have an equal angle The internal angles of the equilateral triangle are also the same that is 60 degrees Here are the formulas for area altitude perimeter and semi perimeter of an equilateral triangle Consider an equilateral triangle with side length a Draw a perpendicular bisector of a side and name the perpendicular also called the height of the triangle length as h Now we use the formula for the area of a triangle Area of triangle ABC

Using the formula Area of a Triangle A 1 2 215 b 215 h 1 2 215 4 cm 215 3 cm 2 cm 215 3 cm 6 cm 2 Apart from the above formula we have Heron s formula to calculate the triangle s area when we know the length of its three sides Also trigonometric functions are used to find the area when we know two sides and the angle To find the area of a triangle whose length of three sides is given First find the semi perimeter of the triangle s a b c 2 where a b and c are the length of the three sides of the triangle Then find the value of s a s b and s c Lastly find
Area of Scalene Triangle Formula For finding out the area of a scalene triangle you need the following measurements a The length of one side and the perpendicular distance of that side to the opposite angle b The lengths of all three sides Heron s Formula for Equilateral Triangle As we know the equilateral triangle has all its sides equal To find the area of the equilateral triangle let us first find the semi perimeter of the equilateral triangle will be s a a a 2 s 3a 2 where a is the length of the side Now as per the heron s formula we know
