Question

In ∆PQR, A, B and C are the midpoints of PQ, QR and RP respectively. If perimeter of ∆ABC

is 18.6 cm, then perimeter of ∆PQR is _________cm.​

Answer 1

Answer:

9.3cm

Step-by-step explanation:

Since,A,B and C all are midpoints.

Therefore,

By midpoint theorem, perimeter of ∆ABC=Half of perimeter of ∆PQR=18.6/2=9.3cm
