​

Answer 1

Answer:

Step-by-step explanation:

First rectangle with sides 3 cm and 2 2/3 cm

therefore perimeter= 2 (l +b)=2( 3 + 2 2/3)= 2 ( 3 + 8/3)= 2 x  17/3=34/3 cm

Second rectangle with sides 4 3/4 cm and 1 1/2 cm

Perimeter= 2 (4 3/4 + 1 1/2)= 2 ( 19/4 + 3/2)= 2 x  25/4= 25/2 cm

Total perimeter= 34/3 +25/2 = 68/6 + 75/6+ 143/6 = 23 5/6 cm
