If other than 8 inches wide and 12 inches long is in large to a poster. If the width is in large to 24 inches what is the length of the poster?
since the width is 3 times as big,
the length will also be multiplied by 3, right?
Not quite sure what "other than" is supposed to be, but it is apparently rectangular in shape
and "in large" should be "enlarged"
