Let the lengths be 2x and 5x
If: 2*(2x+5x) = 224 then x = 16 So therefore the lengths are 32 and 80 because 32+80+32+80 = 224
Perimeter is easy. Just add up all of the sides. However, if you are missing some measurements, then things could be more complicated. Please specify next time.
What does '136',7 cm' represent??? The perimeter, a side, or a diagonal. Please clarify.
If there's a two foot border around a 14 x 20 foot area, that makes it 18 x 24 feet, with a perimeter of 84 feet.
If you want to ask questions about "this", then I suggest that you make sure that "this" does appear in the question.
Perimeter: add the three sides. Area: Use the formula area = (1/2) x base x height. Please note that the height must be measured perpendicular to the base. Depending on the data known, you might also use other formulae; for example, if you know the lengths of the three sides, you can use Heron's formula - if you need it, look it up on the Wikipedia.
You CAN'T calculate the perimeter of a rectangle, knowing only its diagonal. You do need some additional information about the rectangle - such as its width, or its length, or perhaps the length/width ratio.

To figure that out, you must multiply the width and length 2x since in a square or a rectangle is 2 width and 2 length. and when you must mutiplied it, the answer to both length and width, you must add and that is how you figure out the perimeter of a square or a rectangle. This is for 5th graders who is struggling on geometrey. I'm a perfect A+ student in 5th grade that posted the answer to this. I hope you like it and recomend it!^^ Please recomend it...:)

There is insufficient information for us to answer this question. Please edit the question to include more context or relevant information, such as the ratio of perimeter to WHAT!
Presumably because it has four right angles and four straight sides that are parallel just like a rectangle has.
A circle is a non-example of rectangle. -(ONE question at a time PLEASE )

By measuring it. If you want to calculate it based on other information you know about the rectangle, please clarify what information you know.
