Question

if sides of triangle is 51m 37m and 20m then find area

Answer 1

We know that S = (a + b + c)/2

                           = (51 + 37 + 20)/2

                           = 54m.

We know that Area = root s(s-a)(s-b)(s-c)

                                 = root 54(54 - 51)(54-37)(54-20)

                                 = 306.


Hope this helps!
