Answer:
1.77
Step-by-step explanation:
5 because you have to divide 60 by 12.
Either twice or more than twice. But I’d go with twice
You simply put 40 over a hundred and 55 over n (which is the number were trying to find) so you do cross multiplication. 55 times a hundred and after you get the answer. You divide it by 40 and should get 137.5.
You multiply 6ftx20ft then add 1 to it to get your answer
