Determine the formula, in terms of x, that best describes the area of the plot.
1 answer:
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:
Expand
Evaluate the like terms
Hence, the area of the plot is 2x^2 -x - 1
