$5\ \text{ft}$

Step-by-step explanation:

Perimeter of rectangular lot = $448\ \text{ft}$

The width of the easement is $x\ \text{ft}$

Buildable area 140 ft by 64 ft

$2(140+2x)+2(64+2x)=448\\\Rightarrow 140+2x+64+2x=\dfrac{448}{2}\\\Rightarrow 204+4x=224\\\Rightarrow x=\dfrac{224-204}{4}\\\Rightarrow x=5\ \text{ft}$

The width of the easement is $5\ \text{ft}$ .
