The answer depends on what the 25 cm is a measure of!
Then the square will have 4 equal sides of 5cm with a perimeter of 20cm and an area of 25 square cm
20 cm
The perimeter is 7 cm
If it's a regular decagon then its perimeter is 10*25 = 250 cm
Area of square: 1/16 square cm
The perimeter of a square, if it has an area of 25 cm, is: 20 cm
Side of the square = 25/4 = 6.25 cm Area = 6.25*6.25 = 39.0625 square cm
20 cm
20 cm
Since it is a square, all four sides are the same. The side is sqrt(25 cm2) = 5 cm. The perimeter is 4 x 5 cm = 20 cm.
Then the square will have 4 equal sides of 5cm with a perimeter of 20cm and an area of 25 square cm
The area of square is : 400.0
