Question

If △PQR ~ △ABC, PQ = 6cm, AB = 8cm and perimeter of △ABC is 36 cm, then perimeter of △PQR is ?

Answer 1

Answer:

∆PQR ~ ∆ABC, PQ = 6 cm, AB = 8 cm and perimeter of ∆ABC is 36 cm, then perimeter of ∆PQR is

Answer 2

Answer:

The perimeter of the two triangles are also in proportion with the sides.

Step-by-step explanation:

GIVEN: triangle PQR and triangle ABC are similar and

PQ=6cm,

AB=8cm,

and perimeter of triangle ABC is 36cm

To find: perimeter of triangle PQR.

• The perimeter of the two triangles are also in proportion with the sides.
• This proportion can be written.
• On rearranging the perimeter of the triangle PQR can be found
• Therefore the perimeter of triangle PQR is 20.25cm.sq.

Hence, the perimeter of triangle PQR is 20.25cm.sq.
