help plzzzzz........ ​

Answer 1

$\Large{\underbrace{\sf{\pink{Answєr:}}}}$

$\huge{\boxed{\sf{\orange{9 \sqrt{15}}}}}$

$\Large{\underbrace{\sf{\red{Explanatíon:}}}}$

α = 12cm,

b = 12cm

Pєrímєtєr = 30cm

:$\implies{\sf{α+b+c=30}}$

:$\implies{\sf{12+12+c=30}}$

:$\implies{\sf{24+c=30}}$

:$\implies{\sf{c=30-24}}$

:$\implies{\sf{c=6cm}}$

$\displaystyle{\sf{semíperímeter= \dfrac{30}{2}cm=15cm}}$

$\displaystyle{\sf{ \therefore Area\:of\:the\:triangle}}$

Heron's Formulae :-

★$\large{\sf{\boxed{\blue{ \sqrt{s(s-a)(s-b)(s-c)}}}}}$★

:$\implies{\sf{ \sqrt{15(15-12)(15-12)(15-6)}}}$

:$\implies{\sf{ \sqrt{15(3)(3)(9)}}}$

:$\large\implies{\boxed{\sf{\purple{ 9 \sqrt{15}cm^{2}}}}}$
