Answer:
C. 8.56cm
Step-by-step explanation:
Since we are to get the difference of cord length in centimeter, there fore we will have to convert the one yard and one metre length of wires to centimeters.
For 1m length of cord
1m = 100cm
For 1yard length of cord
1yard = 91.44cm
Difference in cord length = 100cm - 91.44cm
= 8.56cm
