one centimetre
You cannot calculate lengths to percentages. Percentages are comparisons of two related quantities so you can have one length as a percentage of another length, but not by itself.
Assuming those are the lengths of the four sides, it can have almost any angles.Assuming those are the lengths of the four sides, it can have almost any angles.Assuming those are the lengths of the four sides, it can have almost any angles.Assuming those are the lengths of the four sides, it can have almost any angles.
Depends on the size of the pool - assuming that that is what the question is about.
Assuming there is no waste, you will get exactly 10 lengths of rope all 2 metres long.
Add up the lengths of all the sides.
By adding the lengths of the 5 sides together.
If you are given two lengths with the units of centimeters just multiply the two cm lengths and you have cmxcm which is cm2
Assuming you want to measure lengths, meters are commonly used.
Assuming these number are the coordinate pairs of a triangle then use Pythagoras to determine the lengths of the sides. Then use Hero's formula to calculate the area from the sides. Beyond that I can't be bothered to do it.
The calculators have been programmed in such a way that they are able to calculate sin, cos and tan without the side lengths.
That depends on what you mean by "calculate". There are 12 of them but their lengths depend on having a lot more information.
You multiply the 3 lengths of the box.
