please answer directly​

Answer 1

Answer:

Here is your answer

Step-by-step explanation:

The circles with maximum area and given condition will have diameter= 7cm

Area of circles=πr2+πr2=722×(27)2+722×(27)2=277+277=77

Area of cardboard =14×7=98  (Since it is a rectangle)

Remaining area =98−77=21 sq. units
