semi perimeter=51+37+20÷2
s=108÷2=54cm
s-a=54-51=3cm
s-b=54-37=17cm
s-c=54-20=34cm
area \: of \: the \: triangle = \sqrt{s(s - a)(s - b)(s - c)} sq \: unitsareaofthetriangle=
s(s−a)(s−b)(s−c)

=
\sqrt{54 \times 3 \times 17 \times 34}
54×3×17×34
=
\sqrt{3 \times 3 \times 3 \times 3 \times 17 \times 17 \times 2 \times 2}
