Total Coverage area= $1500 km^2$

Radius of cell (r) = $2km$

Area of hexagonal cell = $2.6* r^{2}$

= $2.6*4$

= $10.4 km^2$

Total no of cell sites required to cover entire coverage area = $\frac{total \ coverage \ area}{cell \ area}$

= $\frac{1500}{10.4}$

= $144.23$ cell sites

Thus 144 cell sites would be required assuming hexagonal shaped cells to cover a given area.
