Assuming you're measuring a rectangle... Okay - you know the length of one side (10m), and the perimeter (36m) The two sides you know total 20m, therefore the sum of the other two sides MUST equal 16m divided by 2 = 8m.

How do you find a missing value in a rectangle?
For a side, one side is equal to the other side. If you don't know the other side, even if you know one side and the perimeter/area, you can calculate it algebraically. For example, if you want to find the perimeter of a rectange with one side who's length is 7. Because the other side's length is 7, you can add that to get 14. Then use the perimeter formula P=2L+2W to calculate it. Suppose the perimeter is 30. You can plug that into the formula as well as put in 14 for 2L or just put in 7 for L. Then subract 14 from both sides of the formula to get 16=2W. Then just divide by 2 to get W=8, which would be equal to the missing sides of the rectangle.
What is length of the side of a square if its perimeter and area have the same value?
4 units
How do you calculate perimeter in acres?
There is no one answer, it depends on the shape. The smallest value of perimeter will be for a circle. For a four sided shape the smallest will be for a square, for a rectangle the perimeter gets bigger the longer and narrower the area becomes. Knowing the area in acres gives the number of square yards only, you have to know either the length or width, work out the width or length as the case may be, then just add up the four sides.

What are length and width of a rectangles sides which has an area of eighteen meters squared and a perimeter of eighteen meters?
Area can never be as low as the perimeter value -- impossible question.No impossible if read correctly...18 meters squared is the area and 18 meters is the perimeter.

How does increasing the dimensions of a rectangle impact the perimeter?
If you increase the rectangle's length by a value, its perimeter increases by twice that value. If you increase the rectangle's width by a value, its perimeter increases by twice that value. (A rectangle is defined by its length and width, and opposite sides of a rectangle are the same length. The lines always meet at their endpoints at 90° angles.)

A shape with the same area and perimeter?
As a perimeter is a measure of length and has different units to those measuring an area then it is the numerical value that is the same. CIRCLE : area = perimeter occurs when πr2 = 2πr = : r = 2 SQUARE : area = perimeter when d2 = 4d : d = 4, where d is the length of a side.
How do you calculate the top dimensions of a rectangle if you know its perimeter and bottom area?
Important to note are these formulae: Perimeter_of_rectangle = 2 x (length + width) Area_of_rectangle = length x width So if the perimeter and area are known, then: 2 x (length + width) = perimeter => length + width = perimeter / 2 => length = perimeter / 2 - width length x width = area => (perimeter / 2 - width) x width = area (substituting for length given above) => perimeter / 2 x width - width2 = area => width2 - perimeter / 2 x width + area = 0 which is a quadratic and can be solved either by factorization or by using the formula: width = (perimeter / 2 +/- sqrt(perimeter2 / 4 - 4 x area)) / 2 = (perimeter +/- sqrt(perimeter2 - 16 x area)) / 4 This will provide two values for the width. However, each of these values is the length for the other, so the larger value is the length and the smaller value is the width. Sometimes only 1 value will be found for the width above. In this case, the rectangle is actually a square which means that the length and width are both the same. Examples: 1. perimeter = 6, area = 2 width2 - perimeter / 2 x width + area = 0 => width2 - 6 / 2 x width + 2 = 0 => width2 - 3 x width + 2 = 0 => (width - 2) x (width - 1) = 0 => width = 2 or 1. So the length is 2 and the width is 1. 2. perimeter = 12, area = 9 width2 - perimeter / 2 x width + area = 0 => width2 - 12 / 2 x width + 9 = 0 => width2 - 6 x width + 9 = 0 => (width - 3)2 = 0 => width = 3 So the rectangle is a square with both length and width of 3.

How do you find the area of a rectangl if you only have the perimeter?
With great difficultly. The area could be any value greater than 0 units2 and less than or equal to the area of a square with the given perimeter which would be 1/16 x perimeter2 units2. To know which of the possible areas you would need to know the length of one side, then you can work out the area: perimeter = 2 x (length + width) ⇒ width = (1/2 x perimeter) - length ⇒ area = length x width = length x ((1/2 x perimeter) - length) = (1/2 x perimeter x length) - length2
What is the formula to calculate the perimeter of a triangle with b equals 5cm h equals 4cm and an unknown side?
If you know only the base and height, you have two unknown sides and it is not possible to calculate the perimeter. The perimeter can have any value greater than or equal to 5+sqrt(89) cm.
How can you find the perimeter of a hexagon with one side missing?
You cannot. The missing side can have any value greater than 0 and less than the sum of the five known sides - and there is no way to know which.
How do you turn an area into a perimeter?
Shapes have areas and perimeters. Since the value of the area is in square units and the perimeter is not, you don't convert one to the other but sometimes you will be able to find out one value if you have the other. Squares are easiest. The area is found by multiplying one side by another. Finding the square root of that number will give you the length of one side. Multiplying that side length by 4 will give you the perimeter.
