There is no exact answer. The answer would be any two numbers totaling eleven between 5 and 6.
21 x 2 has greatest perimeter
There is no limit to the size of the perimeter.
The two are measured in different dimensions of units and are therefore incomparable.
The dimesions are: 4.5 cm and 7.5 cm Check: 4.5+7.5+4.5+7.5 = 24 cm
Yes.

7.5cm x 4.5cm
Of course, a rectangle can have a greater perimeter and a greater area. Simply double all the sides: the perimeter is doubled and the area is quadrupled - both bigger than they were.

Yes.
39
The length is x units and the width is 18-x units, for all values of x that are greater than 9 and less than 18 units.
yes it will have a greater area
It depends on the sizes of the two shapes.
yes it can; a rectangle 5 by 2 has perimeter 14 and area 10 for example; a rectangle 10 by 2 has perimeter 24 and area 20, both greater.
