The Perimeter $P$ Of a Rectangle with Length I and Width W Is

question 7

Multiple Choice

The perimeter $P$ of a rectangle with length I and width W is given by the formula $P = 2 l + 2 w$ . Solve this formula for W . If the perimeter of a certain rectangle is 46.54 meters and its length is 16.25 meters, find its width.

• A) \(w = \frac { P - 2 l } { 2 } ; w = 4.83 \mathrm {~m}\)
• B) \(w = \frac { 2 l - P } { 2 } ; w = 7.02 \mathrm {~m}\)
• C) \(w = P - 2 l ; \quad w = 14.04 \mathrm {~m}\)
• D) \(w = \frac { P - 2 l } { 2 } ; w = 7.02 \mathrm {~m}\)
• E) \(w = 2 l - P ; \quad w = 4.83 \mathrm {~m}\)
