I’m beyond lost. I really struggle with geometry

Same. You should use Desmos online graphing calculator if you have anymore problems like this. You just put it into the calculator and it graphs the line. In this case, the line must be perpendicular to the line CD, basically a horizontal version of the line. I put all of these into Desmos and the one that is perpendicular is -0.5x + 5.5. Hope this will help you in the future!

Determine the formula, in terms of x, that best describes the area of the plot.

liq [111]

The area of a plot is the amount of space on the plot

The area of the plot is 2x^2 -x - 1

<h3>How to determine the area</h3>

The dimensions of the plot are given as:

Length=2x+1

Width=x-1.

The area of the plot is the product of its dimension.

So, we have:

$Area = (2x + 1)(x - 1)$

Expand

$Area = 2x^2 - 2x + x - 1$

Evaluate the like terms

$Area = 2x^2 -x - 1$

Hence, the area of the plot is 2x^2 -x - 1
