16 square cm.
40cmIf the square has an area of 100 square centimetres, then each side is 10 centimetres long. With four sides, this gives a perimeter of 10 x 4 = 40 centimetres.
A metre is a distance - a square metre is an area. A square metre is the area occupied by a square which is 1 metre long on all sides. It is also the area occupied by any rectangle whose sides, when multiplied together, give a figure of 10,000 square centimetres... so a rectangle with sides of 50 centimetres and 200 centimetres, or a rectangle with sides of 80 centimetres and 125 centimetres.... and so on.
It will be 4 square centimetres.
Square root of the area.
The area of square is : 100.0
To find the length of the sides of a square given its area, you take the square root of the area. In this case, the area is 25 square centimeters. The square root of 25 is 5, so each side of the square is 5 centimeters long.
The area of a square is calculated by squaring the length of one of its sides. For a square with sides that are 10 cm long, the area is (10 , \text{cm} \times 10 , \text{cm} = 100 , \text{cm}^2). Therefore, the area of the square is 100 square centimeters.
