The area is directly proportional to both the length andwidth of a rectangle. Thus if one is halved then the area is also halved.
It becomes a bigger rectangle - possibly a square.
A square is a special kind of rectangle ... one that happens to have equal length and width.

A square is a rectangle that just happens to have all its sides of equal length. That is the only instance in which a rectangle is a square, so no. A rectangle is not always a square.
The perimeter of a rectangle is given by the formula P = 2(l + w). It is clear that as the length, l, increases, the perimeter, P, increases, as well. We say, therefore, that P is directly proportional to l. If l is the length and b is width of a rectangle then, the perimeter P of the rectangle is 2(l + b) units. P = 2(l + b) P = 2l + 2b If have b as a constant then, 2b will be a constant. Now l is the varying quantity. Say 2b = K P = 2l +K Perimeter changes if the length of the rectangle changes. In particular, if the length increases the perimeter of the rectangle increases. Similarly, if the length decreases the perimeter also decreases. So, the perimeter is directly proportional to the length of the rectangle.

So obviously the perimeter is directly proportionate to its length (and its width).
the area also doubles
The length of the rectangle is 18cm. The width of the rectangle is 9cm.
As the speed and length of a wave decrease, the frequency remains the same while the wavelength decreases. This means that the wave's energy decreases as well.
if the length is 36 on a rectangle then what is the width of the rectangle
The perimeter decreases by 4. Decreasing the length by 4 decreases the perimeter by 8. Increasing the width by 2 increases the perimeter by 4. -8+4=-4 For example: Area of a rectangle could be: 8 x 6 (8 being the length and 6 being the width). The perimeter is 8+8+6+6=28 If the length is decreased by 4 then it becomes 4 If the width is increased by 2 then it becomes 8. The perimeter becomes 4+4+8+8=24
A rectangle only has 2 dimensions. The longer one is usually called the length, and the shorter one is usually called the width. But if the rectangle happens to be standing up on one of its sides, then either the length or width may become its height. Whenever you see "height" of a rectangle, that number will be either the length or the width of the rectangle when the drawing is lying flat on the desk.
The width and length of a rectangle are two of its main dimensions. The width is the measurement of the shorter side of the rectangle, while the length is the measurement of the longer side. The area of a rectangle is calculated by multiplying the width by the length.
