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.

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 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 + 40âˆš2 to 2âˆš800 + 2(âˆš800âˆš2). You can never derive the exact perimeter of a figure from an area alone.

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.

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

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

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.

The answer is irrational and the only way to give an exact value is to give it as 13200*sqrt(6) ft.

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.

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 Ã— âˆš25, which equals 4 Ã— 5, which equals 20.

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 + 40âˆš2 to 2âˆš800 + 2(âˆš800âˆš2). You can never derive the exact perimeter of a figure from an area alone.

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.

The exact answer will depend on what information you have. But generally speaking, Surface area = Perimeter of cross section x Length
