- perimeter is also multiplied by 'K'

- area is multiplied by K2

- volume is multiplied by K3

The answer depends entirely on how the dimensions change. It is possible to change the dimensions without changing the perimeter. It is also possible to change the dimensions without changing the area. (And it is possible to change the area without changing the perimeter.)

Area is like the perimeter, only you multiply the dimensions, the definition of Area is the inside of a 2-d Figure

perimeter.

What I think is that the perimeter is the distance around a figure. :)

Add all measurements of the sides on the figure

Sum of dimensions of all sides

to measure the perimeter we need a figure with boundaries and all the sides with dimensions

The perimeter is doubled.

You can't. The perimeter doesn't tell the area. There are an infinite number of shapes with different dimensions and different areas that all have the same perimeter.

44 x 1.5 = 66.

When the linear dimensions of a plane figure are quadrupled, its perimeter is quadrupled, and its area is multiplied by 42 = 16 .

The absolute value of the perimeter doesn't change, only the unit value which increases by a factor of 3.

Area is like the perimeter, only you multiply the dimensions, the definition of Area is the inside of a 2-d Figure

The distance round a closed figure is the perimeter.

A figure that has an area of 5 units [base x height] has the obvious dimensions 1 and 5 since 5 is a prime number. If the figure is a rectangle then the dimensions can be : length= 5 height= 1. Area= 5 x1= 5cm^2 Perimeter= 5+5+1+1=12cm

If the new linear dimensions are k times the old dimensions, then the new area is k2 times the old area.
