Question 899759
Use Heron's formula to calculate the area															
HERON”S FORMULA															
															
Area of Triangle =		{{{sqrt(s*(s-a)(s-b)(s-c))}}}													
where s = half the perimeter				a,b,c are the sides of the triangle											
a=	5	b=	7	c=	10										
															
S=	{{{(a+b+c)/2}}}				S=	11									
															
Area ={{{sqrt(	11	*	(	11	-	5	)(	11	-	7	)(	11	-	10	))}}}
Area ={{{sqrt(	11	*	(	6	)(	4	)(	1	))}}}						
															
Area ={{{sqrt(	264	))}}}													
Area =	16.25	square cm
