The rectangle below has an area of 4(x+3) [4 is width, x+3 is length] square units. when the dimensions of the rectangle are doubled, the area of the new rectangle in terms of x is 8(2x+6). [ 8 being the width and 2x+6 being the length.] will the ratio of the area of the original rectangle to the larger rectangle be the same for any positive value of x?

Yes it will be. The ratio will always be

4(x+3)/8(2x+6)
4x+12/16x+48

ratio = 1/4

You can test this out by substituting some values of x.

For example,

x=1
Orig=16 New=64
16/64=1/4

x=2
Orig=20 New=80
20/80=1/4

and so on...
