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.

To find the perimeter of a square, you need to know the length of one side. Since the block is 6000 square meters, we need to calculate the side length of the square. To do this, we take the square root of the area, which is the square root of 6000, approximately 77.46 meters. The perimeter of a square is calculated by multiplying the side length by 4, so the perimeter of a 6000 square meter block would be 4 x 77.46 = 309.84 meters.
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.
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
