The perimeter of a rhombus does not provide enough information to determine angles.
80 mm
You don't have enough information. If the area in question is a circle, the perimeter (circumfrence) is about 31.7 inches. If it is a square, the perimeter is about 35.8 inches. and if the area is a very long and thin 80 inches by one inch, the perimeter is 162 inches. You need to know the shape; even though many shapes might have an area equal to 80 square inches, the perimeter will vary depending on shape.
Area of square 400 so dimensions 20 x 20 making perimeter 80
80 acres of land is equivalent to 32.37 hectares.

A 20-unit square has a perimeter of 80 units.
Any length you want above about 1.373km as long as the enclosed area is 15ha.
The perimeter is 35.78 inches.
I believe you've already found it.
In a square, if perimeter=80 meters, then side=20 meters, and area= 400 square meters.
If a square has a perimeter of 80 meters, then each side is 20 meters in length. (80/4 sides of a square=20) The area of a square is side2, so 20*20 equals 400. The area of a square that has a perimeter of 80 meters is 400 meters2.
The perimeter of a rhombus does not provide enough information to determine angles.
Any distance from 12280 metres upwards.If the area in question is in the form of a circle, it will have a perimeter of approx 12280 metres.To see how the perimeter can increase without limit, let x be any positive number.Let y = 12000000/x.Then a rectangle with length x metres and breadth y metres will have an area of 1200 hectares. Its perimeter will be 2(x + y) metres which is more than 2x metres. But x can have any value so 2x can be made as large as you like. And the perimeter will be [at least, slightly] larger still.

It is: 120+80+120+80 = 400 feet
