Which formula shows how the length of the rectangle can be determined by the width and perimeter? p=2l+2w

(P/2) - W = L

Step-by-step explanation:

P = Perimeter

W = Width

L = Length

Formula of Perimeter

=> P = 2L + 2W

Now, let's simply that formula to make L alone.

=> P/2 = 2L/2 + 2W/2

=> (P/2) = L + W

=> (P/2) - W = L + W - W

=> Length = (P/2) - W

For example, let's take the perimeter of a rectangle is 14cm. Its width is 2cm. Length is L

Using the formula,

=> (P/2) -  W = L

=> (14/2) - 2 = L

=> 7 - 2 = L

=> L = 5

Let's plug in our answer.

=> 2(5) + 2(2) = 14

=> 10 + 4 = 14

=> 14 = 14

So, our formula is correct.

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 %
