Area of a circle = πr^{2}

Area of the 50 circles = 50π(25)^{2} = 98,175 ft^{2}

Is it the area inside the circles being watered? If so that is 98,175 ft^{2}

The area outside the circles would be 192,500-98,175 ft^{2} = 92,325 ft^{2}

If the diameter of each circle is 50 ft then only 77 can fit in the rectangle.04/08/20
