Write two simultaneous equations and solve them. One for the perimeter, one for the area.
Area: 54 square cm Perimeter: 30 cm
It can be 56.25 or anything less, but not more. You can't tell the area from the perimeter, and you can't tell the perimeter from the area. -- if each side is 7.5, the perimeter is 30, and the area is 56.25 -- if it's (5 by 10), the perimeter is still 30, and the area is 50 -- if it's (4 by 11), the perimeter is still 30, and the area is 44 -- if it's (3 by 12), the perimeter is still 30, and the area is 36 -- if it's (2 by 13), the perimeter is still 30, and the area is 26 -- if it's (1 by 14), the perimeter is still 30, and the area is 14

There is no such thing as the area of the perimeter. A perimeter is a length and so has only 1 dimension. As such, its area is 0.
