You cannot figure out the length of an octagon without a lot more information. Alternatively, you can measure the lengths of the sides.
It can be used as a side length, which has many possibilities to figure with.
To create a triangle, the sum of the two shorter sides must be greater than the third side. If one of the sides of length 10 is the longer side then the missing side must be greater than 10 - 10 = 0 If the missing side is the longest side then the missing side must be less than 10 + 10 = 20 Thus any length that is greater than 0 and less than 20. Examples include: 1, 5, 10, 19
To create a triangle, the sum of the two shorter sides must be greater than the third side.If the side of length 10 is the longer side then the missing side must be greater than 10 - 8 = 2;If the missing side is the longer side then the missing side must be less than 8 + 10 = 18.Thus any length that is greater than 2 and less than 18.Examples include: 7, 10, 8, 4.
To create a triangle, the sum of the two shorter sides must be greater than the third side. If the side of length 13 is the longest side then the missing side must be greater than 13 - 5 = 8 If the missing side is the longest side then the missing side must be less than 13 + 5 = 18 Thus any length that is greater than 8 and less than 18 Examples include: 9, 12, 17 If the third side is 12, the triangle is a Pythagorean triangle.
scale factor
Multiply (the length of one side) by (the length of one side).
Of what?
Perimeter = 5*26 = 130cm Missing length = 130-23.3-30.4-44.9 = 31.4cm
Because there is no information on which side is the hypotenuse, there is not a unique answer. The hypotenuse can either be the missing side or c. If the hypotenuse is the missing side, then it has a length of sqrt(2594) = 50.93133 units. If c is the hypotenuse the missing side is 12 units long.
It is the side of an isolateral figure.

You need to know the proportionality constant, or ratio of the two figures. Suppose two corresponding sides have lengths of 10cm and 25cm, then the ratio is 25/10 = 2.5. If another side of the first figure is 6cm long, then multiply it by 2.5 to find the length of the corresponding side: 6cm x 2.5 = 15cm. If one side of the second figure is 30cm long, then divide it by 2.5 to get the length of the corresponding side in the first figure: 30cm / 2.5 = 12cm.
The length of the other side is: 28.6 cm
Here's a sneaky way to do it, based on an ancient secret of wisdomfrom the Himalayan caves of Nepal and Tibet:If you're sure it's a square, and you know the length of any side,then the missing side has the same length as the one you know !
