L=1.5w
It means that there is always a constant ratio, which is 1 1/2 between the length and the width. So if you know the dimension of either one, you can calculate the dimension of the other. Example: Suppose that the width = 10. Now you can calculate that the length = 15. Second example: What is the width if the length is 45? Now use the relationship given to calculate that the width is 30.

The length of a rectangle is equal to three times its width if the perimeter is equal to 168 feet what is the length of the rectangle?
63 feet
The length of a rectangle is three times its width If the perimeter of the rectangle is 486in2 what is its area?
the length is equal to 160,083
If you know the perimeter and lenght of a rectangle and want to find its width do you divide the perimeter by the length?
No. If you draw a rectangle there are four sides, the length of two of those sides are equal to the length, and the other two are equal to the width. Therefore: the perimeter, which is equal to all the sides added up, is equal to two times the length plus two times the width: or 2L+2W= Perimeter. If you know L and you know the perimeter you can solve it algebraically. the width equals the perimeter minus two times the length, all that divided by two, or W= (P-2L)/2 (when you do the algebra). you might be thinking about the area in which case if you knew the area and the length and you want to find the width you would divide the area by the length.
How do you work out the length and width of a square?
The length and width of a square are equal. Thus, find the square root of the area and the answer = length= width.
How do you find length in the area of rectangle and its width?
multiply length times height times width
