A regular dodecagon is a polygon with 12 equal sides.
Length of each side = 108/12 = 9 cm.
Length of the apothem = (9/2)/tan 15 = 9/2tan 15 = 16.79 cm
Area of each triangle = 9/2(16.79) = 75.57 cm^2
Therefore, area of the dodecagon = 12(75.57) = 906.9 cm^2
It is about $5.89 for one pair of work gloves. You divide 494.92 by 84 (7 dozen) and that is your unit price.
It would be 180 inches per second
reason: there are 12 inches in a foot so you multiply 12 times 15 and get 180:)
