The correct answer is 10 times the square of 2. You must use the Pythagorean Theorem, which is a2+b2=c2. The sides if the square measure 10 cm because adding all four sides will give you the perimeter of 40 cm. Replace a and b with 10 and solve for c.

What is the perimeter of a 6000 square meter block?
That depends on the exact form of the block - whether it is square, or different forms of rectangles. The perimeter to area ratio is not the same for all shapes.
What is the perimeter around 800 square feet?
The perimeter outside a rectangle with an area of 800 square feet can vary from 113.137... feet to 802 feet. In a triangle, it can vary anywhere from 80 + 40√2 to 2√800 + 2(√800√2). You can never derive the exact perimeter of a figure from an area alone.
What is the perimeter of 48 acres?
There's no way of knowing unless we know the shape. 48 acres is 232320 square yards. That could be a patch of land 10 yards wide and 23232 yards long, making the perimeter 46484 yards. If it was a square it would be about 482 yards on a side, making the perimeter 1928 yards.
The area of a square garden is 25 square feet. what is the length of each side?
A square garden is to enclose and area of 540 square meters. Give the exact answer and appto image the length of one side of the garden to the nearest the tenth of a meter
What is the area and perimeter of a square whose diagnol has a length of 10 square root of 2?
To answer this you've got to see that a square can be told as two equal triangles joined, right? Ok, so, next, you use known ways to calculate remaining sides/angles/both of a triangle (for instance, if there are two angles with 30º each, the remainig will be 120º , so it gets a total of 180º, but that is not the exact purpose of this question, only of a step of it, so I won't go too far with it): So, each of the two triangles that form a square would have two angles of 45º each (forming one of 90º joined with the other triangle's). Then, if 1 side (lets say, side "c") has sqrt(10) of length, then each (lets say) "a" and "b" (remaining ones of the triangle) would have a lenght of about 2.236067977498. So, what do we know now? We know that each smaller side of the triangle has 2.236067977498, and that will correspond to the length of each of the square' s sides. So, for the perimeter: 2.236067977498x4=8.944271909992 For the area: 2.236067977498x2.236067977498=4.999999999991996234340004
What is the approximate length of each side of the square?
The approximate length of each side of a square is one-fourth of the entire perimeter. Each side of a square is always 1/4 of the perimeter. However, the exact approximation may vary because the perimeter of the square is not provided nor can be derived.
What is the perimeter length of an exact square lot containing 1500 acres?
The answer is irrational and the only way to give an exact value is to give it as 13200*sqrt(6) ft.
Is it possible to evaluate the exact diagonal length of a square using Pythagoras theorem?
That depends how exactly the measurements of the sides are - and how exactly the "right angle" is really a right angle. If the measurements are exact, then, yes, you can also calculate the diagonal exactly - using Pythagoras' Theorem..................................................................................................................................Improved Answer:No it's not possible to find the accurate length of the diagonal of any square using Pythagoras' theorem because the answer will always be an irrational number which can never be determined just like the value of pi in a circle.
What is the perimeter of a square with an area of 25 sq?
All you need to do to find this is realize two things:The area of the square will be the exact square of the length of it's sides.The square has four sides of the same length, so it's perimeter will be four times the length of one of those sides.The way to get the answer then is to take the square root of the area, and multiply it by four. We're told that the area is 25, so the area is 4 × √25, which equals 4 × 5, which equals 20.
Perimeter of a leaf?
Measure the outline of the leaf; the exact perimeter will vary with the size of the leaf.
A square has an area of 42 square inchesWhat is the exact length of a side of a square?
The exact length of one side of the square is the square root of 42. My calculator only goes to 7 decimal places, so I cannot give the exact dimension.
What is the perimeter of a 6000 square meter block?
That depends on the exact form of the block - whether it is square, or different forms of rectangles. The perimeter to area ratio is not the same for all shapes.
The perimeter of a rectangle is 30 inches if the length is more than the width what is the width?
You don't have enough information to find the exact length of the width, but the width has to be less then 7.5 if it smaller then the length.
What is the length and width of 846 square feet?
if your object is a rectangle then it is not possible to figure out the exact length of and width because we do not know the ratio of the length to width. if your object is a square then... the length is 29.08607914 the width is 29.08607914
What is the perimeter around 800 square feet?
The perimeter outside a rectangle with an area of 800 square feet can vary from 113.137... feet to 802 feet. In a triangle, it can vary anywhere from 80 + 40√2 to 2√800 + 2(√800√2). You can never derive the exact perimeter of a figure from an area alone.
It was designed to be a 50 foot square. But the science club needed one half of the area for a native plant garden. The playing surface was cut in half diagonally. What is the perimeter of the area?
If I understand your question correctly, there is a square that is 50 feet on all four sides, and then a line is placed through the square diagonally, and you need to figure out the perimeter of the triangular "half square" created by this diagonal line. If this is the case, you must use the Pythagorean Theorem. The Pythagorean Theorem states that for any right triangle: a^2 + b^2 = c^2 Where c is the hypotenuse, and a an b are the sides that make the right angle. Since a and b are both 50, the equation we must first solve is: 50^2 + 50^2 = c^2 2500 + 2500 = c^2 5000 = c^2 ~71 = c So, the length of the diagonal line is approximately 71 feet. The other sides are 50 feet each, so the entire perimeter is approximately 171 feet. If you require and exact answer, it is 100 + √5000.
Surface area formula of a prism?
The exact answer will depend on what information you have. But generally speaking, Surface area = Perimeter of cross section x Length
