to have a perimeter of 80cm the sum of the 4 sides must be 80cm. If it is a rectangle then the sides are unequal and the internal corners are 90 degrees. Adjacent sides have to add up to 40cm and can be any a+b=40 where a does not equal b. 0.1cm and 39.9cm is a valid answerso is 15cm and 25cm - anything that adds up to 40 except 20+20 which would be a square not a rectangle

What is the perimeter of a rectangle with an area of 24cm?
The perimeter of the rectangle is the sum of its 4 sides.
How do you find out the perimeter?
The perimeter of any 2D shape is the sum of all of the individual sides. For example: the perimeter of a rectangle is = length of rectangle (top) + length of rectangle (bottom) + height of rectangle (Left) + height of rectangle (Right)
What is the perimeter of a rectangle that has the radious of 15mm and 20mm?
The perimeter of a rectangle is the sum of its 4 sides.
The length of a rectangle is twice its width If the perimeter of the rectangle is 54y find its area?
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
What is the perimeter of a rectangle with two 5cm squares?
the perimeter of a rectangle with two 5cm squares will be 30cm
What measurements do you need to find the area and perimeter of a rectangle how would you use these measurements to find the area and perimeter of a rectangle?
you need length and width length multiply width = area length + length + width + width = perimeter
How to get the deminsions of a rectangle?
The dimensions of a rectangle are the length and the width. With these two measurements , the area of the rectangle can be calculated : Area = length x width. The perimeter can also be found : Perimeter = (2 x length) + (2 x width).
What is the perimeter of a rectangle 8mx3m?
Add the two known measurements together, then multiply by 2 - and you'll have your answer !
What measurements do you need to find the area and perimeter of a rectangle how would you use these measurements to find the area and perimeter of a square?
The lengths of the base and the side. You would multiply these to get the area and would double sum of the two to obtain the perimeter measurement.
How do you find the perimeter of your desktop?
To find the perimeter of a desktop, first measurements need to be taken. The basic formula for perimeter of a rectangle is found in adding all the side lengths together.

How does doubling the side lengths of a rectangle affect its perimeter?
Both the side lengths and the perimeter are linear measurements, therefore they are proportional. In other words, twice the side length results in twice the perimeter.
How do you find the perimeter of a triangle with the perimeter of a rectangle?
There is no reason for the perimeter of a triangle to have any relation to the perimeter of an unrelated rectangle!
If BC16.5 and CD4.5 what is the perimeter of the rectangle?

What is the common perimeter of a rectangle and a trapezium?
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.
