Thank you again Ms. Sue for your help..math makes me crazy :)

College Algebra
okay..I drew the rectangle..18*2=36 length. The widths must make the perimeter greater than 78 cm.. I took 78-36 to get 42 and divided it by 2 for the two width sides and got 21. You stated that the width must be shorter than the length..21 cm is not shorter than 18 (Length).....

..so I want to multiply 18 by two to get 36? I got that..I am stuck on the area that says "what widths will make the perimeter greater than 78 cm?"..I appreciate your response, but am still confused..math is my downfall for sure. Is my final answer of 42 correct or d...
