Question

the semi perimeter of the triangle is 6 CM its sides of length 3 cm 5 cm and 4 cm what is the area of the triangle

Answer 1

Hi,



Semi perimeter ( S ) = 6 cm




Let A = 3 cm , B = 5 cm and C = 4 cm



Therefore,



S - A = 6 - 3 = 3




S - B = 6 - 5 = 1 cm



And,


S - C = 6 - 4 = 2 cm




Therefore,



Area of triangle = ✓S ( S - A ) ( S - B ) ( S - C )




=> ✓6 × (3 ) × ( 1 ) × (2)



=> ✓ 6 × 6


=> ✓36


=> 6 cm².



Hence,


Area of triangle = 6 cm².

Answer 2

your answer is 6 cm^2.
