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!

How do you find the width of a rectangle if you know the perimeter and the length?
Perimeter = 2 * width + 2 * length, so rearranging --> width = (Perimeter / 2) - length
How do you find the length and width if you know the perimeter?
Length + width = half of perimeter, so you need more information...
How do you find perimeter without knowing the length or the width?
If you do not know the length and width of ALL sides, then as far as I know it isn't possible to find the perimeter unless you measure each side and then find it.
How do you find the perimeter of a rectangle with only the width or length and the area given?
It not possible you nit witt that is not true length x width = area If you know length and area, solve width width = area / length then 2 x length + 2 x width = perimeter
How do you find the base of a rectangular prims if you know the length width and perimeter?
It isn't clear how you would define the "perimeter" for a 3D figure. The base is the product of length x width.

Can you find the perimeter and length if you know the area and width?
no

How can you find the perimeter of a rectangle if you know its length and width?
The formula for perimeter is 2l+2w or 2*length + 2*width. This means that you multiply the length by two and multiply the width by two. Then, you add the two products together to find the perimeter.
How do you find the length and width of a rectangle if you only know the perimeter the perimeter is 26?
Its impossible to isolate both the length and width, but you can figure out the sum of one pair of length and width, which is 13.
How would you find the width if you only know the perimeter and length?
If it's a rectangle, just minus the length from the perimeter twice and than divide what you have by 2. Width = (Perimeter - (length*2))/2

If you know a perimeter of a square but not the length or width how do you find the area?
Divide the perimeter by 4 and then square the result to find the area of the square.
How do you find the area and the width when you know the perimeter and the length?
Divide the perimeter by 2 and subtract the length to get the width. Multiply the length by the width to get the area. P=2L+2W P-2L=2W (P/2)-L=W A=LW
How do i find the length and width if you only know the perimeter?
if it is a square...divide by 4 If it is not a square you cannot find the length and width because it can be short and wide or tall and narrow.
