If the perimeter and the length of a rectangle are known, the width can be calculated using the formula:
Width = P/2 – l
, where l = length of the rectangle; and w = width of the rectangle, and P = perimeter of the rectangle.
How do you find length and width from perimeter?
To find the width,
multiply the length that you have been given by 2, and subtract the result from the perimeter
. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.
How do you find the length of a rectangle when given the perimeter?
To find the perimeter of a rectangle,
add the lengths of the rectangle’s four sides
. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.
How do you find the length and width of a rectangle if you know the perimeter and area?
The formula for the perimeter, ‘P’ of a rectangle whose length and width are ‘l’ and ‘w’ respectively is P = 2(l + w). To calculate the length and width of a rectangle first, calculate the value of width ‘w’ by using the area of rectangle formula that is,
‘w = A/l’
.
How do you find the length and width of a rectangle when given the area?
To calculate the length and width of a rectangle first, calculate the value of width ‘w’ by using the area of rectangle formula that is,
‘w = A/l’
.
What is the perimeter formula?
| Table 1 . Perimeter Formulas | Shape Formula Variables | Square P= 4s s is the length of the side of the square. | Rectangle P=2L+2W L and W are the lengths of the rectangle’s sides (length and width). | Triangle a+b+c a,b , and c are the side lengths. |

What is length and width?
Length refers to the distance between two ends of an object.
Width refers to the measuring the breadth or how wide the object is
. Length can be measured in geometry by considering the biggest side of the object. Width can be measured in geometry by considering the smallest side of the object.
How do you find the dimensions when given the area and perimeter?
The formula for the perimeter, ‘P’ of a rectangle whose length and width are ‘l’ and ‘w’ respectively is P = 2(l + w). To calculate the length and width of a rectangle first, calculate the value of width ‘w’ by using the area of rectangle formula that is,
‘w = A/l’
.
How do you find the perimeter with the area?
To get the perimeter from the area for a square,
multiply the square root of the area times 4
. Perimeter is always measured in linear units, which is derived from the area’s square units.
How do you find the length and width?
Substitute the values of Area in the formula ‘
A = l × w’
and simplify to find width ‘w’ in the form of length ‘l’.
How do you calculate the dimensions?
To calculate dimensional (DIM) weight,
multiply the length, width, and height of a package, using the longest point on each side
. Then, divide the cubic size of the package in inches by the DIM divisor to calculate the dimensional weight in pounds.
What is the height of a rectangle?
Divide the volume by the product of the length and width
to calculate the height of a rectangular object. For this example, the rectangular object has a length of 20, a width of 10 and a volume of 6,000. The product of 20 and 10 is 200, and 6,000 divided by 200 results in 30.
What is a perimeter in math?
The perimeter is
the total measurement of all the edges of a shape
e.g. a triangle has three edges, so its perimeter is the total of those three edges added together. … The perimeter of a rectangle can be calculated by adding the length and width together and doubling it.
How do we calculate area?
We measure area in square units : cm2 or m2. Area is
calculated by multiplying the length of a shape by its width
. In this case, we could work out the area of this rectangle even if it wasn’t on squared paper, just by working out 5cm x 5cm = 25cm2 (the shape is not drawn to scale).
