The length of a rectangular lot is 7 yards less than twice its width. if the length was increased by 11 yards and the width decreased by 6 yards, the area would be decreased by 40 square yards. find the original dimension of the lot.

The width = 16 yards and the length = 25 yards.

Step-by-step explanation:

Let x yards be the original width, then the original length is 2x - 7 yards.

Therefore the original area = x(2x - 7) yd^2.

The new area =  (2x - 7 + 11)(x - 6)

= (2x + 4)(x - 6) yd^2.

So we have the equation

x(2x - 7) - (2x + 4)(x - 6) = 40

2x^2 - 7x - (2x^2 - 12x + 4x - 24) = 40

2x^2 - 7x - 2x^2 + 8x + 24 - 40 = 0

x - 16 = 0

x = 16 yards = the width.

The length = 2(16) - 7 = 25 yards.

i would pic false cause it goes down towards negative
