   Methods to Find the Area of a Triangle

   Area of a triangle can be found using three different methods. The three different methods are discussed below

   Method 1

   When the base and altitude of the triangle are given.

   Area of the triangle, A = bh/2 square units

   Where b and h are base and altitude of the triangle, respectively.

   Method 2

   When the length of three sides of the triangle are given, the area of a triangle can be found using the Heron’s formula.

   Therefore, the area of the triangle is calculated using the equation,

   A = [tex]\tt\sqrt{s(s-a) (s-b) (s-c)}[/tex]

   Where a, b, c are the side lengths of the triangle and s is the semi perimeter

   The value of s is found using the formula

   [tex]\tt{ s = \frac{a+b+c}{2}[/tex]

2. FORMULA ⓵ :

   [tex] \\ [/tex]

   • Area of ∆ = ½ × H × B
   • where ,
   • H → length of ∆
   • B → Base of ∆

   [tex] \\ \\ \\ [/tex]

   FORMULA ⓶ :

   [tex] \sf s \: = \frac{a + b + c}{2} [/tex]

   • where
   • a , b , c are sides of ∆
   • s means semi–perimeter

   [tex] \\ [/tex]

   [tex] \sf Area \: = \sqrt{s(s – a)(s – b)(s – c)} [/tex]

   [tex] \\ \\ \\ [/tex]

   FORMULA ⓷ :

   [tex] \\ [/tex]

   Name of Formula = Pythagoras Theorem

   [tex] \\ [/tex]

   USES OF THIS THEOREM :

   • This helps to find any side of the right angle ∆

   [tex] \\ \\ [/tex]

   Formula :

   • ( BASE )² + (HEIGHT ) ² = ( HYPOTENUSE )²
   • simply , as (B)² + (A)² = (H)² also we can write
   • where ,
   • B denote Base of right angle ∆
   • A denote Altitude of right angle ∆
   • H denote Hypotenuse of right angle ∆
