Question

in a triangle P, Q,R are mid points of sides BC, CA, AB respectively. if AC=21cm BC=29cm, AB=30m find the perimeter of the quadrilatral ARPQ​

Answer 1

See the figure above.

As we know, AB = 30

AR = AB/2= 30/2 = 15

Similarly,

AQ = 21/2

By Heron's Formula, find the length of side PR and PQ.

Then add all the values to find the Perimeter.
