60 cm
Step-by-step explanation:
Parallelogram ABCD is shown in attached diagram. The diagonals of the parallelogram bisect each other, so
AE = EC
BE = ED
Ib DE = 3y + 6 cm, BE = 5y - 10 cm, then

Now, EC = 2y + 4, so

Since AE = EC, then AE = 20 cm
The brace that connects points B and D has the length

The brace that connects points A and C has the length

Answer:

Step-by-step explanation:
probability of selecting a girl from students is 
probability of girl wearing sneaker from girls is
or
