The perimeter is a total measurement of all sides of an object or figure. You didn't indicate what you were measuring so it is difficult to answer your question. Different objects have different sides and different lengths. Assuming, however, that you are finding the perimeter of a square with a side of 6.9 cm, then the perimeter would be 6.9 x 4, since all sides of a square are the same. 6.9 cm x 4 = 27.6 cm. To find the perimeter of a rectangle, multiply 2 times the length and add 2 times the width.
The area of square is : 1936.0
3 cm x 6 sides = 18 cm perimeter
15 cm
100 cm
Since a square has 4 sides, if each side is 7.5 cm long, then the perimeter is 4 x 7.5 cm = 30 cm.
Perimeter of a square = 4 x side units Side = 19 cm So, Perimeter = 4 x 19 cm = 76 cm
Perimeter of a square = 4*side = 4*3 cm = 12 cm.
The perimeter of a square with a side measuring 4.5 cm is 4 times 4.5 = 18 cm
Perimeter = 4*22 = 88 cm
If a polygon with a perimeter of 30 centimeters has sides with length 6 cm/side, then it has 30 cm / 6 cm per side = 5 sides. So a regular pentagon with a side length of 6 cm has a perimeter of 30 centimeters.
perimeter of octagon is 128 cm= 8 * side side of the octagon=128/8=16 cm
If each side of a square is 10 cm, the perimeter is 4 x 10 cm = 40 cm.
The area of square is : 1936.0
The perimeter would be 18 cm.
The side of a regular hexagon is 4.8 cm. Find its perimeter.
The answer depends on what information you do have: the length of a side, or a diagonal, the area, ... If a side is of length s cm then the perimeter is 4*s cm.
3 cm x 6 sides = 18 cm perimeter
