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
