Question

Find the area of a triangle having sides 50cm,78cm, and 112cm

Answer 1

HERE,a=50cm,b=78cm,c=112cm

WE MAY USE THE HERON'S FORMULA

$s = \frac{a + b + c}{2}$

$s = \frac{50 + 78 + 112}{2}$

$s = \frac{240}{2}$
s=120cm

WE KNOW THAT,
$\sqrt{s(s - a)(s - b)(s - c)}$
=area of triangle........(herons formula)

ACCORDINGLY,

AS SHOWN IN IMAGE ,THE AREA OF TRIANGLE FOR THE GIVEN SIDES IS 1680sq.cm

HOPE THIS HELPS!!!
