168.
In 60 cm width you can place 12 (60/12) circles of 5cm radius. Let us treat it as one row of 12 circles.
In 70 cm length you can place such 14 rows (70/5).
Therefore, total number of circles that can be put in rectangle 60*70= 14*12=168.Ans.

Answer:
The radius is 5cm so the diameter is 10cm.
Therefore, you can have 6 circles one way and 7 the other (60/10 and 70/10).
6*7=42.
Answer, 42.
