The length of a rectangle is four times its width.
1 answer:
Answer:
Pretty Simple!
Step-by-step explanation:
First, what you have to know is that the formula for the area of a rectangle is:
(Length times Width equals the Area.)
Knowing this, we can input 100yd^2 into the equation.
Also, we know that the Length is equal to four times the Width.
Meaning that, we can substitute L with 4W.
Thus:
So, all we have to do now is solve!
Now, multiply that by 4, and we get 20:
That's it!

The number of rows in the arena is 26
<h3>How to determine the number of rows?</h3>The hockey arena illustrates an arithmetic sequence, and it has the following parameters:
- First term, a = 220
- Sum of terms, Sn = 10920
- Common difference, d = 16
The number of rows (i.e. the number of terms) is calculated using:
So,we have:
Evaluate the terms and factors
Evaluate the like terms
21840 = n(424+ 16n)
Expand
21840 = 424n + 16n^2
Rewrite as:
16n^2 + 424n - 21840 = 0
Using a graphical tool, we have:
n = 26
Hence, the number of rows in the arena is 26
