Answer:
Your question was very confusing but I tried...
Step-by-step explanation:
Area = 8,100 square feet
area of a square = a²
8,100 square feet = a²
√8,100 square feet = √a²
90 feet = a
total length each row of bookshelf is 4/5 of the length of the storage space.
90 feet * 4/5 = (90*4)/5 = 360/5 = 72 feet.
Area = (72 ft)²
Area = 5,184 square feet.
Hope this helped :)
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)](https://tex.z-dn.net/?f=Area%20%3D%20%282x%20%2B%201%29%28x%20-%201%29)
Expand
![Area = 2x^2 - 2x + x - 1](https://tex.z-dn.net/?f=Area%20%3D%202x%5E2%20-%202x%20%2B%20x%20-%201)
Evaluate the like terms
![Area = 2x^2 -x - 1](https://tex.z-dn.net/?f=Area%20%3D%202x%5E2%20-x%20-%201)
Hence, the area of the plot is 2x^2 -x - 1
