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)
A quadrilateral polygon
Any rectangle whose sides are in the ratio 2:3. For example, in a 6x9 rectangle, the width (6) is two-thirds of the height (3), so it is similar to the 2x3 rectangle.
a parallelogram is always a example of a rectangle a rhombuz and a trapezoid
No.For example, a 1 metre * 72 metre rectangle and a 8 metre * 9 metre rectangle both have areas of 72 square metres. But the perimeter of the first is 146 metres while that of the second is 34 metres.
Any rectangle will do as an example.
A rectangle is always a quadrilateral and a parallelogram.
Rectangular prism
Multiply the length of the rectangle by the width. For example: 34cm x 20cm = 680cm2
All rectangles are parallelograms but a rhombus for example, is a parallelogram but not a rectangle.
A example would be a rectangle pool, and a book/dictionary. Hope it helped! :)

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)
In order to find the area of a rectangle, multiply the length by the width of the rectangle. For example: If the length of a rectangle is 5cm and the width of a rectangle is 2cm, then the area of the rectangle would be 5cm X 2cm = 10cm².
