Length = 2W

P= 2L + 2W
60 = 2(2W) + 2W
60= 4W +2W
60 = 6W
60/6W = 6W/6W
w = 10
Length = 2(10)
Length = 20

P= 2L + 2W
60= 2(20) + 2(10)
60= 40 +20
60 = 60

alexgriva [62]

Answer:

The answer to your question is 43.7 g of chocolate

Step-by-step explanation:

Data

56% cocoa

mass of a chocolate bar = 78 g

Process

To solve this problem, use proportions and cross multiplication, consider the mass of the bar is 100%.

                          78 g of chocolate ------------------- 100%

                             x                          ------------------    56%

                                            x = (56 x 78) / 100

                                            x = 4368/100

                                            x = 43.68 g

-Round to the nearest tenth

             Mass of the chocolate = 43.7 g
