Answer:
B is answer
Step-by-step explanation:
Answer:
P = length + width x 2
P = 3.5ft + 5.5ft x 2
P = 9ft x 2
P = 18ft + 1.5ft (the new mural)
P = 19.5ft
Therefore the perimeter of Rosalie's new mural is 19.5ft
Sine is also known as Opposite over hypotenuse.
I wrote your answer on the paper...
You would take 1818÷33=55.09
55.09 is how many toothpicks it took for each step made
Then you would take 55.09×55=3029.95
You can make sure this is correct by taking 55.09×33=1817.97 which would actually be 1818 because you had to round it up
