the length of the rectangle can be represented by (x-4) and its width can be represented by (2x-7) what are the dimensions of the rectangle in centimeters ?

Question

I need help with this question 

Answer 1

You need more information to get any unique solution

but Area = LW = (x-4)(2x-7) = 2x^2-11x + 28

and

Perimeter = 2(L+W) = 2(2x-7+x-4) = 2(3x-11) = 6x -22

That's not much but if you did know either the area or perimeter, you could figure out L and W
