Q. The perimeter of a rectangular rug is 22.44 meters. The length of the rug is 00.88 meters. What is the width in meters of the rug?\newlineA. 0.4 m 0.4 \mathrm{~m} \newlineB. 0.8 m 0.8 \mathrm{~m} \newlineC. 3 m 3 \mathrm{~m} \newlineD. 1.6 m 1.6 \mathrm{~m}
  1. Perimeter Formula: The formula for the perimeter PP of a rectangle is P=2(length+width)P = 2(\text{length} + \text{width}). We are given the perimeter P=2.4P = 2.4 meters and the length 0.80.8 meters. We need to find the width.
  2. Denote Width as ww: Let's denote the width as ww. According to the perimeter formula, we have:\newline2.4=2(0.8+w)2.4 = 2(0.8 + w)
  3. Isolate Length + Width: To find the width, we first divide both sides of the equation by 22 to isolate the length + width term:\newline2.42=2(0.8+w)2\frac{2.4}{2} = \frac{2(0.8 + w)}{2}\newline1.2=0.8+w1.2 = 0.8 + w
  4. Solve for Width: Now, we subtract 0.80.8 from both sides to solve for ww:\newline1.20.8=w1.2 - 0.8 = w\newline0.4=w0.4 = w
