Answer:
The length of the pig pen for fencing the plans is 28 feet .
Step-by-step explanation:
Given as :
The measure of the fencing = 186 feet
The width of the pig pen = w = 15 feet
Let the length of the pig pen = l = x feet
Now, To find the measure of the fencing , we calculate the perimeter of the plans .
So, <u>From perimeter method</u>
I.e Perimeter = 2 × Length + 2 × Width
or, 186 feet = 2 × l + 2 × w
Or, 186 feet = 2 × l + 2 × 15
Or, 186 - 2 × 15 = 2 × l
or, 186 - 30 = 2 × l
Or, 2 × l = 156
∴ l = = 78 feet
So, The length of pig pen = l = 28 feet
Hence The length of the pig pen for fencing the plans is 28 feet . Answer
