Enter value

cm

Answer 2

Answer:

Step-by-step explanation:

A=18cm, B=10cm, and C=14cm

Semi perimeter=$\frac{a+b+c}{2} </p><p>=\frac{18+10+14}{2} </p><p>=\frac{42}{2}</p><p> =21$

Area of triangle= $\sqrt{s(s-a)(s-b)(s-c)} </p><p>=\sqrt{21(21-18)(21-10)(21-14)} </p><p>=\sqrt{21*3*11*7} </p><p>=21\sqrt{11}$
