Answer: The amount of fencing needed can be expressed as 6x + 6 ft and, the cost of fencing can be expressed as Cost = 18x + 18
Step-by-step explanation: The dimensions of the rectangular garden are given as
Length = 2x + 3
Width = x
The amount of fencing that he would need is simply the total measurement all around the rectangular garden, that is, the perimeter. The perimeter of a rectangle is given as follows;
Perimeter = 2(L + W)
With the dimensions already provided we can now substitute for the values
Perimeter = 2(2x + 3 + x)
Perimeter = 2(3x + 3)
Perimeter = 6x + 6
Therefore the amount of fencing needed can be written out as,
6x + 6 ft
If however, fencing costs $3 per foot, then the cost of the entire fencing can be expressed as
Cost = 3(6x + 6)
Cost = 18x + 18
Given that Mr.Jone's garden is rectangular in shape, we will begin by solving for the perimeter, this value will describe the entire length of the fencing materials needed.
The expression for the cost is given as
Cost = 18x+8
Given data
Length = 2x + 3 feet
Width = x feet
Cost per foot = $3
Since the shape of the garden is rectangular
The Perimeter of the garden will be
Perimeter = 2(Length)+ 2(Width)
Perimeter = 2( 2x + 3)+ 2(x)
Perimeter = 4x+6+ 2x
Perimeter = 6x+6 feet
This means that the total length of the garden is 6x+6 feet
Let us find the cost
Cost for the fencing material for 6x+6 feet = 3( 6x+6)
Cost = 18x+8
