Find the area of a regular hexagon that has a perimeter of 60in

If hexagon perimeter = 60, then each side = 60/6 = 10

polygon area = n * side^2 / 4 * tan (180/n)

("n" is the number of sides)

polygon area = 6 * 10^2 / 4 * tan (30)

polygon area = 600 / 4 * 0.57735

polygon area = 600 / 2.3094

polygon area = 259.8077422707

polygon area = 259.81 square inches
