A rectangular writing pd is 5/6ft long by 1/2ft wide. A border is to be added round all sides of the writing pad. Use the formula P=2L + 2W to determine the length of the border.

I will assume the border is of uniform width
including the border:
length = 5.6 + 2x
width = 1/2 + 2x
perimeter = 2(5/6+2x) + 2(1/2 + 2x)
= 5/3 + 4x + 1 + 4x
= 8x + 8/3
