l = w+8, (l+4) x (w-1) = lw, lw+4w-l-4 = lw, 4w-l-4 = 0, 4w = l+4, 4w = w+8+4, 4w = w+12, 3w = 12, w = 4, l=12

If the length of a rectangle is increased by 10 and the breadth decreased by 5 the area is unchanged If the length is decreased by 5 and the breadth increased by 4 even then the area is unchanged?

Suppose the dimwnsions of the rectangle are L and B Then area = LB. Now (L+10)*(B-5) = LB so that 10B-5L = 50 and (L-5)*(B+4) = LB so that -5B+4L = 20 Solving these two equations simultaneously, gives L= 30,B = 20


If the length of a rectangle is tripled what will be the effect on it's area?

If the length is tripled but the width remains unchanged, then the area is tripled.


How does doubling the height affect the volume?

If all other dimensions are left unchanged, doubling the height doubles the volume.


How does the volume of a cube change if the length of one side is increased by one unit another side is decreased by one unit and the third side is left unchanged?

Not enough information: Both the change in absolute terms, and the percentage change, would also depend on the original size of the cube.


Will changing the dimensions of a cylinder affect the volume?

Yes. Except that there will be some combinations of changes to diameter and height which will leave the volume unchanged.

How many doubling the width of a box affect its volume?

If the other dimensions (length and height) are left unchanged, doubling the width will double the volume.


What is the L x W x H for 5.21 cubic meters?

The dimensions of a cuboid cannot be determined from its volume. You could, for example, double the length and halve the width: that would leave the volume unchanged but the dimensions will be different.


How does a volume of a rectangular prism change if the length is tripled?

If only the length is changed and all other dimensions left unchanged, the volume will also triple.


What happens to frequency of a wave when the wavelength is decreased and when the wavelength is increased?

When wavelength decreases, frequency increases, and when wavelength increases, frequency decreases. The product of (wavelength) times (frequency) is always the same number ... the speed of the wave. So when one of them changes, the other one must change in the opposite direction in order for their product to remain unchanged.
