The perimeter is 60 mm
Six cm per side.
20 cm
The answer is 45.72 centimeters. One inch is equal to 2.54 centimeters. To convert inches into centimeters, multiply the inches by 2.54.
The perimeter of this square measures 4 x 1 = 4 decimeters. As 1 decimeter = 10 centimeters then 4 decimeters = 4 x 10 = 40 centimeters.

it would be 21/3
The answer depends on how many sides the shape has. For each number of sides (≥ 3), there is a shape that will meet the requirements of the question.
A perimeter is a measure of distance, typically in linear units (such as centimeters, meters, or feet). The length of the perimeter will depend on the shape being measured. For example, the perimeter of a square with sides of 10 cm each would be 40 cm, while the perimeter of a circle with a radius of 5 cm would be approximately 31.42 cm.
500. Half a meter on each side.
You haven't given any measurements so I cant calculate it. Convert the centimetre side to metres by dividing by 100 and add all sides together to get the perimeter
