A rectangle has four sides joined by right angles between adjacent sides. There are two pairs of two equal sides, having lengths A and B.
To find the perimeter you add up all the sides, A + A + B + B. This may also be written as 2 x A + 2 X B or 2A +2B or 2 (A+B).
To find the area, you multiply A x B.
If A = B then you have a square with perimeter 4 x A and area A2

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.
What are length and width of a rectangles sides which has an area of eighteen meters squared and a perimeter of eighteen meters?
Area can never be as low as the perimeter value -- impossible question.No impossible if read correctly...18 meters squared is the area and 18 meters is the perimeter.
Can different rectangles have the same area and perimeter?
It's very easy for two rectangles to have the same area and different perimeters,or the same perimeter and different areas. In either case, it would be obvious toyou when you see them that there's something different about them, and theywould not fit one on top of the other.But if two rectangles have the same area and the same perimeter, then to look at themyou'd swear that they're the same rectangle, and one could be laid down on the otherand fit exactly.
How does a change in perimeter influence the area of a shape?
There is no systematic relationship between the two. Consider the following 2 rectangles: A = 8 cm * 8 cm: Perimeter = 32 cm, area = 64 cm2 B = 14 cm * 4 cm: Perimeter = 36 cm, area = 56 cm2 The perimeter of B is larger, but the area is smaller.
Can you Find 2 rectangles whose dimensions are whole nos and their area and perimeter is same?
4 x 4 and 6 x 3
