Square county is a square-shaped county divided into 16 equal-sized square districts. if the side length of each district is 4 miles, what is the area of square county?

A square will have the same length and width and area= length times width. its set up in a 4x4 square because there are 16 squares total; 4 across and 4 down. if the sides are 4 miles each then one whole side will be 16 miles. so the equation is 16 times 16 which equals 256. so the answer is 256 square miles.
