Knowing the area doesn't tell the perimeter. There are an infinite number of
different perimeters that can all enclose the same area. The shortest one is
a circle. The next shortest is a square. From there, you can actually make the
perimeter as large as you want, with no limit, while keeping the area constant.
Examples:
30 cm by 40 cm . . . . area = 1,200 cm2 . . . perimeter = 140 cm
10 cm by 120 cm . . . area = 1,200 cm2 . . . perimeter = 260 cm
2 cm by 600 cm . . . . area = 1,200 cm2 . . . perimeter = 1,204 cm
1 cm by 1,200 cm. . . area = 1,200 cm2 . . . perimeter = 2,402 cm
