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.
If you know the dimensions of the missing triangle, then compute the area from those dimensions, then subtract that answer from the area of the full rectangle.
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
the length of a rectangle is 5 more then the width. Find the perimeter and the area of the rectangle
To find a Square in a rectangle first you have to:Make sure the rectangle is Flat.Draw a line straight and exactly in the middle.There you have your two squares in your Rectangle!So just cut a Rectangle in half!
If you know the length of one side - and the area... divide the area by the known side - to get the value of the unknown.
Area of rectangle with part of the shape missing = area of rectangle (lengthxwidth)-area of missing part.

To find a missing measure of the original rectangle, you can use the dimensions of the reduced rectangle, which are scaled down versions of the original's dimensions. If you know one measurement of the original rectangle (either length or width), you can set up a proportion using the corresponding dimensions of the reduced rectangle. By solving for the missing measurement, you can determine the original rectangle's dimensions. This method relies on the fact that the ratio of the sides of the reduced rectangle remains constant with respect to those of the original rectangle.
In a rectangle, each angle HAS to be 90 degrees because -360 divided by four corners= 90 -a rectangle HAS to have 4 right angles
In order to find the perimeter of a 3D rectangle you must gather the lengths of the known sides, calculate the missing rectangular values, and use the formula for perimeter.
You must use the information given that describes that particular rectangle,together with the laws, equations, and formulas you have that relate to theproperties of rectangles, to derive the missing information.The answer will depend on what dimension is missing and what information you do have.
If you know the dimensions of the missing triangle, then compute the area from those dimensions, then subtract that answer from the area of the full rectangle.

To find the missing value in a ratio table, first identify the known values in the corresponding ratio. Use cross-multiplication to set up an equation if necessary. For example, if the ratio of two quantities is known, you can express the missing value in terms of the known values. Finally, solve for the missing value using basic algebra.
A rectangle has no value - experimental or otherwise. Its area has a value, its perimeter, its aspect have values.
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.
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.
