Answer: THERE ARE TWO WAYS OF DOING THIS!!
Key words: square, area, 200 square feet
Area: what × what = 200?
Step-by-step explanation:
A square has 4 sides, and all of its sides are of equal length.
So if a square has 4 sides, and its total area is 200 square feet, what do you have to do?
You have to divide the area by 4!
So 200 ÷ 4 = ?
200 ÷ 4 =50
So each side is 50 feet long.
In this scenario, there are no tenths because each side is exactly 50 feet. If you wanted the lengths to the nearest tenth, your answer would be 50.0

If patio is a square, basically it says the area is where a is equivalent to one side of the square.
Now that we know that a = 200, we will be able to solve the expression
a=
a=14.1421, which is the square root of
Now we rounded to the nearest tenths
a≈14.1
We rounded to 14.1 because the rounding rule is: <em>4 and below rounds down, 5 and above rounds up.</em>
The result is 14.1

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>Answer: There is a linear relationship between the average price of PCs and the number of years that have passed since 2000.
Step-by-step explanation:
From the given graph, we can see there is a straight line , which shows that there is a linear relationship between both quantities.
As the number years increases the average price of PCs decreases.
The given equation of the line is , which shows that the slope of the line is -39, i.e the rate of decrease in the average price of PCs with respect to the the number of years that have passed since 2000.
