Question 319065: The width of a rectangle is fixed at 21cm. What lengths will make the perimeter greater than 74cm?
I want to make sure I am doing this right. If the width is 21, i would multiply it twice. Then the perimeter would need to be greater than 74, so I subtract 42 from 74. This would leave 32 to be divided by two for the length. So the length would have to be more than 32?

Sooo close...74 minus 42 leaves 32 which is TWO times the length, so the length would have to be greater than one-half of 32 or 16.
