The length of the side of a particular square may be expressed as 1200 centimeters, 13.9 yards, 12,000 millimeters, or 0.091 miles. which unit would be best to use to measure the square's perimeter, and would be easiest for the average person to understand? a) centimeters b) miles c) millimeters d) yards

 D)  yards

Step-by-step explanation:   The perimeter of a polygon is equal to the sum of the length of all its sides. All of the units listed will give a correct value for the square’s perimeter. Of these, 13.9 yards is the measurement easiest for the average person to understand.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
