We have a square garden of 400 square foot.
The area of a square is:
where x: side length.
In this case:
![\begin{gathered} A=400=x^2 \\ x=\sqrt[]{400}=20\text{ ft} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20A%3D400%3Dx%5E2%20%5C%5C%20x%3D%5Csqrt%5B%5D%7B400%7D%3D20%5Ctext%7B%20ft%7D%20%5Cend%7Bgathered%7D)
The perimeter of the square is the sum of the lengths of the sides of the square. As they are all equal, we can write:
The fencing is priced at $1.50 per foot. If we add the 7% sales tax to this price we get:
The fencing will be installed in all the perimeter (80 ft).
We can calculate the total cost by multiplying the sales price ($1.605 per foot) and the perimeter (80 ft):
Answer: the fencing will cost a total of $128.40
Ooof, this is a lot! XD, anyway the answer are in the pictures.

I am delighted to assist you anytime.
You would first divide 5 by 8 to get 0.625.
Then you compare.
0.7 > 5/8 (0.625)
Answer:
pi^2
Step-by-step explanation:
If the diameter of a circular rug is 2 feet, we can determine that the rug's radius is 1 foot. We can apply the formula to find the area of a circle
(pi*radius)^2 which would give us and answer of pi^2
