Question

find area of tringle whose sides are 15m ,11m,6m​

Answer 1

$\huge\rm\red{ANSWER }$

______________________

$\huge{Given: }$

⇒Sides: a=15m, b=11m and c=6m

$\huge{Solution :}$

⇒P=15+11+6=32m

⇒Semi perimeter=S= 32/2 , S=16m

⇒A= √s(s−a)(s−b)(s−c). (Heron's formula)

⇒A= √16(16−15)(16−11)(16−6)

⇒A= √16×1×5×10

= √ 800

=20 √2m²
