4. Mensuration Formulas for Triangle

• Area of a triangle= (1/2) (Base × Height) = (1/2) (b × h)
• For a triangle with sides measuring a, b, and c, respectively:
• Perimeter = a + b + c
• s = semi perimeter = perimeter/2 = (a+b+c)/2
• Area of Triangle, A= √(𝑠 − 𝑎)(𝑠 − 𝑏)(𝑠 − 𝑐)
• (This is also known as “Heron’s formula”)
• Area of isosceles triangle =𝑏/4 √4𝑎² − 𝑏²
• (Where a = length of two equal sides, b = length of the base of the isosceles triangle.)
• Area of an equilateral triangle =√ (3/4) ∗ 𝑎²
• (Where a = side of an equilateral triangle)

Right angle Triangle

• Area =1/2(Base x Height)
• Perimeter = Base + Height + Diagonal

Isosceles Right Angle Triangle

• Area = 1/2. a²
• Perimeter = 2a+d
