In the adjoining figure rm and qn are the medians of triangle pqr. if rm=qn, prove by vector method triangle pqr is isosceles

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

its a straight line parallel to the time axis
