Sides of a triangle are a = 16 cm, b = 30 cm and c = 34 cm
s = (16 + 30 + 34)/2 = 80/2 = 40 cm
Area of triangle = √[s(s – a)(s – b)(s – c)]
= √[40(40 – 16)(40 – 30)(40 – 34)
= √[40 × 24 × 10 × 6]
= 240 sq cm
I think the provided option is wrong
s = (16 + 30 + 34)/2 = 80/2 = 40 cm
Area of triangle = √[s(s – a)(s – b)(s – c)]
= √[40(40 – 16)(40 – 30)(40 – 34)
= √[40 × 24 × 10 × 6]
= 240 sq cm
