Step-by-step explanation:
If Sarah bought 12 feet of fabric that was 2 1/3 feet wide to make curtains, this means that the area of the fabric she used for the long set of curtains would be:
Now, if 1/4 of the fabric is 28, then 3/4 would be 84. Now, according to the problem, she used 1/4 of the fabric to make a long set of curtains and the rest to make 5 short sets. Then, 84 ÷ 5 = 16.8, or equivalently:
then, the area of the fabric she used for each of the short sets would be:
we can conclude that the correct answer is:
Answer:the area of the fabric she used for the long set of curtains is:
the area of the fabric she used for each of the short sets is:
