if you change the side length the area will change. It is possible to change them and not change the area. For example make side twice and long and the other half as long. But in general, if you change the lengths of the sides the area of the rectangle changes.
Rectangle area = (rectangle width) x (rectangle height)
Assuming no change in the width, yes.
A = lw Area of a rectangle = length times width
The width of the rectangle will decrease as the length increases .
Area of a rectangle is length X width. All rectangles have opposite 2 sides equal; so that doesn't change anything.
Here's an example: A 4*4 rectangle has the same area as a 1*16 rectangle, but their perimeters are different.
I don't know what you mean by fixed area. All I know is that the area of a rectangle is the length times the width. As long as you don't change the length or the width, or change it into a different kind of shape, this area will remain fixed.
Rectangle area = (rectangle width) x (rectangle height)
Assuming no change in the width, yes.
A = lw Area of a rectangle = length times width
The width of the rectangle will decrease as the length increases .
You wind up with 6 times the original area.
The area of rectangle is : 35.0
Area of a rectangle is length X width. All rectangles have opposite 2 sides equal; so that doesn't change anything.
It's half the area of a rectangle
The area of rectangle is : 48.0
The area of rectangle is : 30.0
