Length + width = half the perimeter, but more info eg area, is needed.
More information is needed. For the same perimeter, the area will vary, depending on whether you have a circle, a square, a rectangle with a ratio of 2:1, a rectangle with a ratio of 3:1, etc.
These two plane figures do not have a common perimeter. As the opposite sides of a rectangle are of equal length then only the measurements of two adjacent sides are needed to calculate the perimeter. (Perimeter = 2A + 2B, where A and B are the lengths of adjacent sides) However, a trapezium does not necessarily have any of its sides of equal length and therefore all four sides have to be measured to determine the perimeter.
If it's a rectangle/parallelogram then 1 metre. If it's not then more info is needed
Further information is needed to provide an answer to this question. If the area is 140 sq units, then this could be formed from a rectangle 1 unit wide by 140 units long - giving a perimeter of 2 x 140 + 2 x 1 = 282 units. But, the rectangle could be 14 units wide and 10 units long giving a perimeter of 2 x 14 + 2 x 10 = 48 units.
This is not answerable in this form because it could have sides of 7,7,1, and 1, or it could have sides of 6,6,2, and 2, among others. More information is needed.
you cannot do that problem with just perimeter. You need to know the area or another dimension like width or length
I want to put a fence up around my yard. My yard is a rectangle measuring 42 feet by 22 feet how many feet of fence do i buy?:perimeter is needed I have a very large living room, it is 70 feet by 15 feet how much carpet do I need to buy?: area is needed THink about them apples.

"Shape" is too general of a term. More information is needed to solve. What kind of shape is it? Triangle, rectangle? is it a regular polygon? See the Related Questions below to get more information.
Area is the number of square unit needed to cover a surface. Perimeter of a figure is the distance around the figure Perimeter is measurements of each sides added.
