The area of the rectangle is 20x^2 - 50x square inches what is the length and width

Answer 1

Area = 20x^2 -50x square inches

A = 10x(x-5). Maybe length is 10x and width =x-5

X>5, x is at least 5 inches

x width Length area

6 1 60 60

7 2 70 140

8 3 80 240

9 4 90 360

...

but from the given information, length and width could be anywhere from zero to infinity. something seems missing from the problem.
