(a) 225 cm²

(b) 225$\sqrt{3}$ cm²

(c) 225 $\sqrt{2}$ cm²

(d) 450 cm²

Answer 1

The area of a triangle having sides a, b, c and s as semi-perimeter is given by,

, where

Therefore the area of a triangle say A, having sides 16 cm, 30 cm and 34 cm is given by

a = 16 cm ; b = 30 cm ; c = 34 cm

Therefore the area of the triangle is
