Width x= 1.57, length 3x=5.7 1.

The area is 5.7 1* 1.57=8.9647.

Square side length: 12.56/4=3. 14.

Square area: 3. 14*3. 14=9.8596.

Radius of circle: 12.56/(3. 14*2)=2.

Circular area: 3. 14*2*2= 12.56.

Maximum circular area

The radiu of that small circle is half that of the large circle,

The area is a quarter of the great circle.

The area of four small circles is equal to the area of the big circle.

So the more materials you use.
