The area of ​​the triangle

area of ​​a triangle

The formula for the area of ​​a triangle

P=\frac {a \cdot h }{2}

 

Legend:

P – area of ​​the triangle

a – the length of the base of the triangle

h – the length of the height lowered to the side a

Sample task:

Calculate the area of ​​the triangle with the base a = 10 cm and the height h = 5 cm

P=\frac {a \cdot h }{2}

P=\frac {10cm \cdot 5cm }{2}

P=\frac {50 cm^{2} }{2}

P=25 cm^{2}

The area of ​​the triangle with the base a = 10 cm and the height h = 5 cm, is 25cm²
