If it's a square: 9 cm
The area of an octagon that has a side length of 2.45m is about 29m2
To find the length of a side of a square when the area is known, you can use the formula: Area = side length². Given that the area is 81 ft², you can take the square root of 81 to find the side length. Thus, the side length is 9 feet.
The area of a square is (the side length)2.That means (the side length) times (the side length).If you multiply 15 by 15, that will get you close.
The term "81 cm²" refers to an area measurement, not perimeter. To find the perimeter of a shape with an area of 81 cm², you would need additional information about its dimensions or shape. For example, if it's a square, each side would be 9 cm, giving a perimeter of 36 cm. If it's a rectangle, different length and width combinations could yield the same area but different perimeters.
Length of Side*Length of Side (in square units).
ok if the perimeter is 36cm and it is a square then you know all four sides are equal 36cm / 4sides = 9cm for each side A = L * W ( both the length and width are 9cm because each side is equal ) A = 9cm * 9cm A = 81cm2
To calculate the area of a square, you multiply the length of one side by itself. The formula is: Area side length x side length.
The area of a square loop with side length a is a2, where "a" represents the length of one side of the square.
Length of a long side x length of a short side = area
The area of an octagon that has a side length of 2.45m is about 29m2
what is the area of a square with a side length of 5x
The area of a square is the square of its side length.
To find the length of a side of a square when the area is known, you can use the formula: Area = side length². Given that the area is 81 ft², you can take the square root of 81 to find the side length. Thus, the side length is 9 feet.
The area of a square is (the side length)2.That means (the side length) times (the side length).If you multiply 15 by 15, that will get you close.

To calculate the area of a regular hexagon, you can use the formula: Area = (3√3 × side length²)/2. Substituting the value of the side length given, the area of a hexagon with a side length of 10 is (3√3 × 10²)/2 = 150√3. Therefore, the area is approximately 259.81 square units.
