How do you find the perimeter of a triangle when you only know the length of 2 sides?
Not possible, you need at least the length of two sides and the included angle.
Can you find a perimeter of a regular polygon if you only know the meaurement of one side?
Only if you know what kind of polygon you have. If you know that you have a hexagon and one side is 1 cm, the perimeter is 6 cm. You only have to know the length of one side, since a regular polygon has equal sides. Perimeter or a regular polygon is the length of each side times the number of sides. You need to know both pieces to find the perimeter. ■
How do you find length and width using only the perimeter?
More information is needed. One of the sides or the diagonal length has to be known, unless you have a square, in which case you divide the perimeter by 4.
How do you find the area of a square with only the perimeter?
its easy really!! All you have to do is divide the perimeter by 4 (because a square has four sides!) once you got that answer you then times that by its self and you have the area!! :)
How do you find the area if the perimeter is only given?
If you are talking about a rectangle, you can't find the area from just the perimeter. With a perimeter of say 80 units, the sides could be 10 and 30, with an area of 300 square units. But the sides could also be 5 and 35, with an area of 175 square units. There are lots of other possibilities. If you are talking about a square, that's different. Each side is a quarter of the perimeter, so the area is a quarter of the perimeter multiplied by a quarter of the perimeter.

What is the formula for finding the perimeter of a pentagon?
The perimeter is the sum of the sides of a polygon. So, to find the perimeter of a pentagon, you need only to add up the 5 side lengths. In the event the pentagon is regular (all equal sides and angles) then you can multiply the measure of the side by 5 to get the perimeter.
How do you find the perimeter of a scalene triangle when you only know two sides and the area?
To get the perimeter, you need to add all three sides. I assume you can get the third side by inserting the numbers you know into Heron's formula.

How do you find the perimeter of a triangle if you only know the length of two sides?
You cannot discover the perimeter of a triangle if all you have is the length of two sides and nothing else. Knowing only the length of two sides of a triangle is insufficient to discover the length of the third side, and, thereby, discover the perimeter. Use the link below to a related question and see how it works.
How do you find the dimensions of a rectangle given only the total perimeter?
Length + width = half the perimeter, but more info eg area, is needed.
How do you find the perimeter of a rectangle with only the slopes given?
You cannot. Given only the slopes, it is impossible to determine the distance between the parallel lines and so the lengths of the sides. Without that you cannot calculate the perimeter.

What is the common perimeter of a rectangle and a trapezium?
These two plane figures do not have a common perimeter. As the opposite sides of a rectangle are of equal length then only the measurements of two adjacent sides are needed to calculate the perimeter. (Perimeter = 2A + 2B, where A and B are the lengths of adjacent sides) However, a trapezium does not necessarily have any of its sides of equal length and therefore all four sides have to be measured to determine the perimeter.
How do you answer a question that only shows one line and it asks for the perimeter?
The perimeter is the length around the outside of a shape, or the total of all the lengths of its sides. A shape that consists only of a line is simple: it has two sides, both of which are exactly the same length (from one end to the other and back along the other side of the line). Just measure the line, then double it. That is the perimeter.
