if a perimeter of a garden is 82 feet. the length is 5 more than twice the width.what is th width of the garden?
P = 2L + 2W
L = 2W + 5
Substitute 2W + 5 for L in the first equation and solve for W, then put that value in the second equation to find L. To check, put both values in the first equation.

the answer is idk
To solve this problem, we need to write an equation based on the given information and then solve it. Let's break down the problem step by step:
Step 1: Assign variables
Let's assume that the width of the garden is "w." Since the length is 5 more than twice the width, we can represent the length as "2w + 5."
Step 2: Write the equation
The perimeter of a rectangle is calculated by adding the lengths of all sides. In this case, the perimeter is given as 82 feet.
The formula for the perimeter of a rectangle is:
Perimeter = 2 * (Length + Width)
Using the variables we assigned earlier, we can write the equation as:
82 = 2 * (2w + 5 + w)
Step 3: Simplify and solve the equation
Let's simplify the equation by distributing the 2 on the right side:
82 = 2 * (3w + 5)
82 = 6w + 10
Subtract 10 from both sides:
72 = 6w
Divide both sides by 6:
w = 12
Step 4: Answer the question
The width of the garden is 12 feet.
Therefore, the width of the garden is 12 feet.
