You add up all the sides together.
If one side says 12 and the other says 6, you add 12+12, then you add 6+6.
12 6 24 + 12 = 36.
+12 +6 The perimeter is 36 ft,in,mm,cm,etc.

What is the peremiter of a parallelogram?
if you are reading this i dont no i was just boerd and i wanted to answer the question lol
What the answer to the perimeter of a pentagon?
Add up all 5 side lengths for the peremiter
What is the peremiter of a rectangle?
The formula for perimeter of a rectangle is: P=2L+2W where L is the length and W is the width of the rectangle.
What is the peremiter of a rectangle with a length of 12Cm and a height of 19Cm?
The perimeter of a rectangle is simply the sum of its four sides. In this case - 12 + 19 + 12 + 19 = 62
What is the formula for the perimeter of a sphere?
In 3-dimensional geometry, the term "perimeter of a sphere" is not normally used.The closest thing would be the equatorial circumference. Think of cutting a ball (with radius r) in half, and looking at the outline of the cut surface. It is a circle with radius r, and the usual circle formula applies:C = 2(pi)r
What is the peremiter around the basseball field?
The perimeter around a baseball field varies depending on the field, however, around the infield, it is always 360 feet; as all the bases are exactly 90 feet from one another.
How do you find length and width of a rectangle when peremiter is given?
You really can't unless you know something else about the length or width or even the area of the rectangle. You have 2 unknowns (length & width) & only one equation (perimeter). In order to find 2 unknowns you need 2 equations, that's why you need to know something else about the rectangle such as how the length & width are related to each or the area of the rectangle. Hope that helps.
What is the octagonal prism volume formula?
v=lxwxhlenght x width x height its actually Bxh where the base is the apothem x perimeter/2(apothem x peremiter/2)xhhaha pwnedThis is pure bullsh*t
If you know perimeter and length how do you find width?
perimeter=2 times length + 2 times width. if the peremiter is 20 and the length was 4, you would do 20=2(4)+2(w) and then 20=8+2w and then subtract 8 from both sides of the = sign. 12=2w and divide both sides by 2 so 6=w. in this case, the width would be 6. hope this helped!
The peremiter of a rectangle is 234 in the length exceeds the width by 39 inches find the length and width?
Since the length exceeds the width by 39 inches, if x is the width, then you can express the length as x + 39. Now, use the formula for the perimeter of a rectangle, replacing known values: perimeter = 2(length + width) 234 = 2(x + 39 + x) Solving this for "x" will result in the width; add 39 to get the length.
