Step-by-step explanation:
Given : Janice puts a fence around her rectangular garden. The garden has a length that is 9 feet less than 3 times its width.
To find : What is the perimeter of Janice fence if the area of her garden is 5,670 square feet?
Solution :
Let the width of the garden be w=x feet.
The garden has a length that is 9 feet less than 3 times its width.
The length of the garden be l=3x-9 feet
The area of the garden is A=5670 square feet.
The formula of area of garden is
Reject x=-42 as measurement cannot be negative.
The width of the garden is w=45 feet.
The length of the garden is l=3(45)-9=135-9=126 feet.
The perimeter of the garden is
The perimeter of Janice fence is 342 feet.
Therefore, Option A is correct.
Answer:
Step-by-step explanation:
<u>Given expression:</u>
<h3>= 2(4f + 2g)</h3>Distribute 2 to both terms.
<h3>= 8f + 4g</h3>We can also split 8f into 4f and 4f.
<h3>= 4f + 4f + 4g</h3>If we take 4 common
= 4(f + f + g)
<h3>= 4(2f + g)</h3>
