Question

In triangle ABC,AB=6cm,BC=7.5cm,AC=6.5cm.the perimeter of the triangle formed by joining the midpoints of triangle ABC is

Answer 1

ans is 17 cm

Let midpoints of AB , BC and CA are P , Q and R respectively. Acordingly to

mid points theorem:-

PQ = AC/2 = 7/2= 3.5 cm……….(1)

QR = AB/2= 12/2=6 cm…………(2)

RP= BC/2=15/2=7.5 cm…………..(3)

Perimeter of ∆PQR= (3.5+6+7.5) cm = 17 cm. Answer.

Answer 2

Answer:

ans 17 centimetres............
