Question

a triangular plot measures 80cm 120cm and 50cm, find the area of plot​

Answer 1

$s = \frac{a + b + c}{2 } \\ a = 80cm \\ b = 120cm \\ c = 50cm$

$area = \sqrt{s(s - a)(s - b)(s - c) }$

$s = \frac{250}{2} \\ s = 125cm$

Hence Area is:-

$\sqrt{125 \times 45 \times 5 \times 75 } \\ area = 1452.36cm {}^{2}$
