There are red blue and white boats in a marina 3/4 of the boats are white 4/7 of the remaining boats are blue and the rest are red if there are 9 boats how many boats are in the marina

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!
