QUESTION

What is the perimeter of a triangle with corners at ##(3 ,4 )##, ##(4 ,2 )##, and ##(8 ,7 )##?

##"the perimeter of triangle is :"14.47" units"##

##"let sides of triangle be a,b,and c"##

##"perimeter of the triangle is s=a+b+c"##

##a=sqrt(5^2+4^2)=sqrt(25+16)=sqrt(41)##

##|a|=6.40" units"##

##b=sqrt(5^2+3^2)=sqrt(25+9)=sqrt(34)##

##|b|=5.83" units"##

##c=sqrt(2^2+1^2)=sqrt(4+1)=sqrt(5)##

##|c|=2.24" units"##

##s=6.40+5.83+2.24##

##s=14.47" units"##
