Okay. Say, for example if you have a perimeter of 36 inches and your width is 8 inches.
Your equation you look like this set up:
P = 2L + 2W
36 = 2L + 2(8)
So,
- First you would finish multiplying: 36 = 2L + 16
- Then you would subtract 16 from each side: 36 - 16 = 2L + 16 - 16
- So it would look like this: 20 = 2L
- Then you would divide by 2 on each side: 20/2 = 2L/2
- So your answer would be 10 = L

How do you determine length if given the perimeter and width?
multiply the width by 2 and then subtract that to the perimeter then divide the answer by 2 to get the length
How do you determine width if the length and perimeter is given?
Subtract two times the length from the perimeter and cut that answer in half.
How can you calculate the length of a rectangle if the perimeter and the width are given?
Because the perimeter is lenght + length +width +width, you do perimeter - double the width, and then halve the remaining number. that should give you the length.
How do you find the length of a rectangle if the perimeter is 40 and the width is 2inches?
perimeter = 2 x (length + width) ⇒ length + width = perimeter ÷ 2 ⇒ length = (perimeter ÷ 2) - width So to find the length of the given rectangle, subtract the width from half the perimeter is how to do it. IF you meant "What is the length..." then: length = perimeter ÷ 2 - width = 40 ÷ 2 - 2 in = 20 - 2 in = 18 in
What is the formula to find the length of a rectangle when the perimeter and width is already given?
Length = (Perimeter - twice width) / 2
How do you find area when given perimeter and width?
If you are given the width and the perimeter, then figure out what the length is then calculate the area... hope this helps :)
What is the width if the perimeter and length are given?
The width would be: P - (L*2) = W*2 Perimeter = P Length = L Width = W
How do you find the length and width of rectangle when given the perimeter but not the width or length?
by appying 2l+2w
What is the width and length when the perimeter is 17.6?
All we can tell from the information you have given is that the length plus the width is 8.8...
What is the perimeter of a room that has a width of Cm and an area of 22m2?
To find the perimeter of the room, we first need to determine its length. Given the area (A) is 22 m² and the width (W) is in centimeters (Cm), we can convert the width to meters (1 Cm = 0.01 m). The formula for area is A = length × width, so length = A / W. Once we have both dimensions in meters, we can calculate the perimeter using the formula P = 2(length + width).
How do you find the breadth of a rectangle from the ratio of length to width if the perimeter is given?
To find the breadth (width) of a rectangle when given the ratio of length to width and the perimeter, you can start by using the perimeter formula: ( P = 2(L + W) ), where ( L ) is the length and ( W ) is the width. If the length to width ratio is given as ( L:W = a:b ), you can express ( L ) as ( L = \frac{a}{b}W ). Substitute this expression into the perimeter formula, solve for ( W ), and then use the perimeter value to find the breadth.
How do you find the perimeter of a rectangle given the length and width?
Perimeter = 2*(L + W).
