For a side, one side is equal to the other side. If you don't know the other side, even if you know one side and the perimeter/area, you can calculate it algebraically. For example, if you want to find the perimeter of a rectange with one side who's length is 7. Because the other side's length is 7, you can add that to get 14. Then use the perimeter formula P=2L+2W to calculate it. Suppose the perimeter is 30. You can plug that into the formula as well as put in 14 for 2L or just put in 7 for L. Then subract 14 from both sides of the formula to get 16=2W. Then just divide by 2 to get W=8, which would be equal to the missing sides of the rectangle.

How do you find the missing length in a rectangle?

That will depend on the information given as for example if you are given its width and area then in order to find its length divide the width into the area.


How do you fine the length in a similar rectangles?

If you are given two similar rectangles, one with all measurements and the other with only one, you first need to find the conversion ratio. Let's call the rectangle that you know everything about, rectangle A, and the other rectangle B. You take the ratio of the side of rectangle B to rectangle A. You then multiply the length of rectangle A by this value, to find the length of rectangle B.


What is the measurement of a rectangle?

A rectangle has a length, a width, and an area. If you know any two of them, you can figure out the missing one.
