Preimeter is a measure of length, area ... well, of area. You can't really compare the perimeter and the area. If both are equal in one unit (like centimeter vs. square centimeter), they won't be equal in another unit (like meters and square meters).
Anyway, to be numerically equal, you must solve the equation area = perimeter. Assuming dimensions of a times b, the equation becomes:
ab = 2(a+b).
Solving for a:
ab = 2a + 2b
ab - 2a = 2b
a(b-2) = 2b
a = 2b / (b-2)
With this last equation, you can substitute any value for b, and get the corresponding value for a. It seems there are infinitely many solutions.

How many rectangles have the same area and perimeter of 18?

How many rectangles have the same area as their perimeter?
The only one I can think of is a square, where Length=Width=4.
If two rectangles have the same perimetre they must have the same area?
No, two rectangles with the same perimeter do not necessarily have the same area. The area of a rectangle is calculated as length multiplied by width, while the perimeter is the sum of all sides. For example, a rectangle with dimensions 2x5 (perimeter 14) has an area of 10, while a rectangle with dimensions 3x4 (also perimeter 14) has an area of 12. Thus, rectangles can have the same perimeter but different areas.
How do you find the area of combined rectangles?
To find the area of combined rectangles, first calculate the area of each individual rectangle by multiplying its length by its width. Then, add the areas of all rectangles together. If the rectangles overlap, subtract the area of the overlapping section to avoid double-counting. Ensure all measurements are in the same unit for accurate calculations.

Is there an example of 2 rectangles with the same area but different areas?
No. Many investigators have searched for such an example, but none have found it yet. According to all published research so far, two rectangles with the same area always have the same area. But the search goes on, in many great universities.

Do two different rectangles with the same perimeter necessarily have the same area?
no
If two rectangles have the same area do they also have to have the same perimeter?
Not necessarily. Let's say that there is a circle with the area of 10. Now there is a star with the area of 10. They do not have the same perimeter, do they? That still applies with rectangles. There might be a very long skinny rectangle and a square next to each other with the same area, but that does not mean that they have the same perimeter. Now if the rectangles are congruent then yes.

How can 2 rectangles have the same area?

If two rectangles have the same perimetre they must have the same area?
No, two rectangles with the same perimeter do not necessarily have the same area. The area of a rectangle is calculated as length multiplied by width, while the perimeter is the sum of all sides. For example, a rectangle with dimensions 2x5 (perimeter 14) has an area of 10, while a rectangle with dimensions 3x4 (also perimeter 14) has an area of 12. Thus, rectangles can have the same perimeter but different areas.
Consider the same pairs of rectangles as above what happens to the area?
There's no way for me to answer that question with the information I have, since there are no rectangles "above".
If 2 rectangles have the same area will they always be similar?
No some times

How would finding the area of a square be the as finding the area of a rectangle?
Squares are rectangles so the formula for area will stay the same.
