Add 3 3/4 to 4 3/4 if it equals 8 you are right
November 24, 2011

Math
No, that isn’t right. Parameter of a rectangle is the sum of 4 sides with opposite sides equal. If width is 4, both sides would be 8. Subtract 8 from 24 to get sum of other two equal sides, which is 16, divided by two would be 8. The length is 8 units.
