If it has a 28 cm perimeter, its sides are length 28/4 = 7. So, the area would be 7 x 7 = 49 cm2.
It is: 6*28*28 = 4704 square cm
It is: 4*7 = 28 cm
Curved surface area: pi*21*28 = 1847.256 square cm rounded to three decimal places
The area of square is the square of one of its sides, which are all equal. To find the value of a side, take the square root of the area. In this case the square root of 49cm2 is 7cm. The perimeter is the sum of all four sides of the square, so the perimeter of a square with an area of 49cm2 is 7+7+7+7 = 28, or 4x7 = 28.
To find the area of a square, you square the length of one of its sides. In this case, if the side length of the square is 12.5 cm, you would square 12.5 to get the area. Therefore, the area of a square with a side length of 12.5 cm is 156.25 square centimeters.
The area of square is : 784.0

7*7 = 49 square cm
The perimeter would be 28 cm
It is: 4*7 = 28 square cm
It is: 6*28*28 = 4704 square cm
Using 3.14 as Pi the area of circle is: 2461.76
The area of rectangle is : 28.0
It is: 4*7 = 28 cm
