Question

p,q,r are the midpoints of sides of triangle abc. find the ratio of perimeter of triangle pqr and triangle abc

Answer 1

ratio of perimeter of pqr and abc = 1: 2
 

hope it helps

Answer 2

Given that P,q, r are midpoints of triangle ABC
So now using mid point we get
Pq=AB/2
Qr=BC/2
Rp=CA/2
Sum of sides
=AB+BC+CA units
Perimeter of triangle PQR = AB/2 + BC/2 + CA/2
=(AB+BC+CA)/2
Now ratio of there perimeter
=1/2
