 yes your first equation is right. original width = w. original length = 2w + 3. New width = w + w = 2w. New length = 2w + 3 + w = 3w + 3. Original perimeter = 2(2w + 3 + w) = 2(3w http://answers.yahoo.com/question/index?qid=201001...
 the given: P=24, L=W+3. plug into the formula. 24=2(W+3)2W. multiply the 2. 24=2W+6+2W. add the 2W's and bring the 6 to the other side by subtraction. 18=4W. divide 18 by 4 to get http://answers.yahoo.com/question/index?qid=201308...
