I think it is 14*7 instead of 14*17.

Since each circle has maximum area,

diameter of each circle = half of length = 7 cm

radius of each circle = 3.5 cm

Area of each circle =${\mathrm{\pi r}}^{2}=\frac{22}{7}*3.{5}^{2}=38.5{\mathrm{cm}}^{2}$

Area of both circles = 38.5*2=77 cm^{2}

Total area = 14*7=98 cm^{2}

Remaining area =98-77=21cm^{2}
