It should be like this
sqrt((p-3q-p+4q)^2+(p-p-q)^2)
= sqrt((q)^2+(-q)^2

ive gotten one more question ..

find the length of the line segments
and assume P > q > 0

(p + 4q, p-q ) and (p - 3q, p )


plzz answer ASAP :)

thaankkzz

sqrt(((p-3q)-(p+4q))^2+((p)-(p-q))^2)=sqrt((p-3q-p-4q)^2+(p-p+q)^2)=sqrt((-7q)^2+q^2)=sqrt(50q^2)=5q sqrt(2)
