Question

D, E and F are the mid-point of sides BC, CA and AB of a △ABC. If AB = 3 cm, BC = 4 cm and CA = 4 cm, then the perimeter of △DEF is ​

Answer 1

Answer:

perimeter= AB+BC+CA

= 3+4+4

= 11

Answer 2

Answer:

5.5cm

Step-by-step explanation:

∆DEF lies on midpoints of ∆ABC

perimeter of∆DEF =1/2×perimeter of∆ABC

=1/2 ×11

=5.5 cm
