Question

If 3 line segments of length 2 cm, 4 cm and 6 cm are taken, then the area of the triangle formed by these line segments is ___.

Answer 1

Using Heron's formula, area of a triangle is A = $\sqrt{s(s-a)(s-b)(s-c)}$.
If s = a, then A = $\sqrt{s(s-a)(s-b)(s-c)}$ = $\sqrt{a\left(0\right)(a-b)(a-c)}$ = 0.
