Question

29.The sides of a triangle are 56cm,60cm,52cm long. Then the area of the triangle is *

Answer 1

1334cm sq. by Herons formula.............

Answer 2

Answer:

semi perimeter = a+b+c/2

=56+60+52/2

=168/2

=84

Using Heron's Formula;

area=$\sqrt{84(140+144+136)} \sqrt[x^{2} 2}$

=$\sqrt{11760+12096+11,424}$

=108.44+109.98+106.88

area=325.3
