Answer:
133.6 cm
Step-by-step explanation:
Length of Frame = 53.6
Length of picture = 53.6 - 2 × Width of Frame
= 53.6 - 2 × 4.1
= 53.6 - 8.2
= 45.4
Similarly ,
Width of picture = 29.6 - 2 × Width of Frame
= 29.6 - 2× 4.1
= 29.6 - 8.2
= 21.4
Now,
Perimeter = 2 ( Length + Width )
= 2 ( 45.4 + 21.4 )
= 2 × 66.8
= 133.6 cm
