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.
