1)Ms.Troy would like you to make a copy of an outfit that she owns and really likes-a sleeveless dress with a short-sleeve jacket. She has selected a lilac linen fabric that comes in 36-in.width. You make a pattern for the dress and record the following measurements:
Jacket back length 15in.
Front skirt length 20 in.
Full back length 41 in.
What length of material do you need to purchase for the dress portion of the outfit?
A)82 in.
B)41 in.
C)70 in.
D)91 in.
What lenth of material do you need for the jacket sleeves?
A)21 in.
B)36 in.
C)27 in.
D)54 in.
To calculate the length of material needed for the dress portion of the outfit, you need to add up the following measurements:
Front skirt length + Full back length = Dress length
20 in. + 41 in. = 61 in.
However, keep in mind that the fabric width is given as 36 inches. So, to accommodate the dress length, you would need to purchase more than just the dress length.
To calculate this, you need to divide the dress length by the fabric width and round it up to the nearest whole number.
Dress length ÷ Fabric width = Number of fabric widths needed to cut the dress portion
In this case:
61 in. ÷ 36 in. ≈ 1.7 (rounded up)
Since you cannot purchase a fraction of a fabric width, you need to round it up to the nearest whole number. So, you would need to purchase 2 fabric widths.
Next, you multiply the fabric width by the number of fabric widths needed:
Fabric width x Number of fabric widths = Total fabric length needed
36 in. x 2 = 72 in.
Therefore, the correct answer for the length of material needed for the dress portion of the outfit is:
C) 70 in. - 72 in. (rounding up to the nearest whole number)
For the jacket sleeves, the question does not provide specific measurements for the sleeve length, so we can't accurately determine the length of fabric needed. As a result, none of the options A), B), C), or D) are correct.
