Question

29. In SABC, it is given that AB =9 cm, BC-6 cm and CA=75 cm. Also, ADEF is given such that EF 8 cm and ADEF - ABC. Then, perimeter of ADEF is (a) 22.5 cm (b) 25 cm (c) 27 cm (d) 30 cm​




please help

Answer 1

Answer:

d.) 30 cm

Step-by-step explanation:

Perimeter of   ⩟ ABC = AB + BC + CA = 9 + 6 + 7.5

                                                                      = 22.5 cm.

∵ ⩟DEF ≅ ⩟ABC

∴ Perimeter⩟(ABC) =  BC

  Perimeter⩟(DEF) =  EF

⇒            22.5                  = 6/8

   Perimeter of ⩟(DEF)

Perimeter(⩟DEF) = 22.5*8/6

                            =30 cm
