The width of the baby blanket is 8 inches.
Solución
The perimeter \( P \) of a rectangle is given by the formula:
\[
P = 2(L + W)
\]
where \( L \) is the length and \( W \) is the width.
Given:
\[
P = 72 \text{ inches}, \quad L = 28 \text{ inches}
\]
Substitute the known values into the perimeter formula:
\[
72 = 2(28 + W)
\]
Divide both sides by 2:
\[
36 = 28 + W
\]
Subtract 28 from both sides to solve for \( W \):
\[
W = 36 - 28 = 8
\]
Thus, the width of the baby blanket is:
\[
\boxed{8} \text{ inches.}
\]

To find the width of the baby blanket, you can use the formula for the perimeter of a rectangle: P = 2(length + width). Since the perimeter is 72 inches and the length is 28 inches, you can set up the equation: 72 = 2(28 + width). Solving this gives you a width of 8 inches. So, a cozy yet slightly unconventional blanket indeed! In knitting, different stitch patterns can affect the dimensions of a finished piece. If Ms. Guy had tried a garter stitch instead of stockinette, her blanket might have had a different final size. It's a fun reminder that yarn and stitches behave uniquely, much like how each project can turn out distinctly, even with the same measurements!
