Area of triangle =
\sqrt{s(s - a)(s - b)(s - c)}s(s−a)(s−b)(s−c)
S=a+b+c/2
a=18 b=15 c=15
S=48/2
s=24
\sqrt{24(24 - 18)(24 - 15) (24 - 15)}24(24−18)(24−15)(24−15)
\sqrt{24 \times 6 \times 9 \times 9}24×6×9×9
\sqrt{6 \times 2 \times 2 \times 6 \times 9 \times 9}6×2×2×6×9×9
=6×2×9
=108 cm^2
hope it's helpful if yes plzzzz mark me as brainliest.
