When the rectangular plot has been fenced all the sides, the length of the fence is the perimeter of the rectangle. Here,
Let the width = x
So the length = 2x + 4 (as per the condition in the problem)
Perimeter 2L + 2B = 2(l+b)
2x+%2B+2%282x%2B4%29 = 500 Ft.
2%28x%2B2x%2B4%29+=+500+Ft.
2%283x%2B4%29+=+500+Ft. Dividing both the sides by 2, we get,
3x%2B4+=+250
3x%2B4-4+=+250-4 = 3x+=+246
So x = 246%2F3 = 82Ft.
2x+4 = 2%2A82%2B4 = 164+4 = 168 Ft.
Width = 82 Ft.
Length = 168 Ft. Answer.
I guess you understood this.
