What is the perimeter of a square with an area of 529 cm2?
92
Detailed Solution Hence, correct answer is 92.
What is the formula area of square?
In other words, the area of a square is the product of the length of each side with itself. That is, Area A = s x s where s is the length of each side of the square. For example, the area of a square of each side of length 8 feet is 8 times 8 or 64 square feet.
How do you find the side length of a square if you know the area?
The area of any quadrilateral can be determined by multiplying the length of its base by its height. Since we know the shape here is square, we know that all sides are of equal length. From this we can work backwards by taking the square root of the area to find the length of one side.
What is the square of 81?
√81 = 3×3 = 9. Hence, the value of the square root of 81 is 9.
How do you find the square root of a 529?
The square root of 529 is the integer which on squaring gives 529. Hence, the square root of 529 is 23. It is written as √529 = 23. Hence, 529 is a perfect square.
How do we find the perimeter of a square?
Since all sides of a square are equal, we only need one side to find its perimeter. The perimeter of the given square is: a + a + a + a = 4 a units. Hence, the formula of the perimeter of a square = 4 × (length of any one side).
What is the perimeter of the square 81 sqm?
Perimeter = 36 m. The area of the square being 81 sq m, each side will be 81^0.5 = 9 m. The perimeter is thus 4 times the side = 4*9 = 36 m.
How do you find the area and perimeter of a square?
The perimeter, i.e., the distance around a square is given by the formula P = 4s since a square has 4 congruent sides of length s. The area of a square is A = s^2, where s is the length of one of the four congruent sides of the square.
What is the area of a square in meters?
Originally Answered: The area of a square is 81 square meters. Find its perimeter? If the area of a square is 81 square meters, its side length is 9 m. (You might need to memorize that 9 × 9 = 81) , A former high school math teacher (Grades 9, 10, and 11). I have a Bachelor of Science Degree in Math Ed. (19…
What is the area of a square with 4 equal sides?
Since a square has four equal sides, P=4S, and the area is A=S^2. and the area of the square is 81, S*S=81, so S^2=81, then S=9. The side lengths are 9 each. 9*9=81.
