Monica has a triangular piece of fabric. The height of the triangle is 21 inches and the triangle's base is 12 inches. Monica says that the area of the fabric is 252 in2. What error did Monica make? Explain your answer by entering the correct area of the fabric.

She didnt divide the product of the base and height by 2

Step-by-step explanation:

The correct answer would be 126 inches squared

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 %
