Question

Find the area of isosceles trangle to using heroes formula

Answer 1

let ABC is an isoscles triangle AB=AC

BC=a AC=b AB=c
b=c

heron's formula

$\sqrt{s(s - a)(s - b)(s - }c )$
$\sqrt{s(s - a)(s - b)(s - b)}$
$\sqrt{s(s - a) ({s - b})^{2} }$
$(s - b) \sqrt{s(s - a)}$
or

$(s - c) \sqrt{s(s - a)}$
