In the figure PQR is an equilateral triangle with each side as 6 cm and O is a point of interior of the triangle. if P,Q and R are respectively the

midpoints of XO,YO and ZO,then find the perimeter of XYZ.
where's the figure?????


In the fig. pq=qr=rq=6cm
now. according to the question, p,q and r are the mid-points
so by mid point theorem,
xy= 2pq, yz= 2qr and zx= 2rp
so the perimeter of xyz = 12 +12 +1 2 = 36 cm
0 0 0
The perimeter of triangleXYZ is 36.
