Answer:
Part a) The scale of the new blueprint is
Part b) The width of the living room in the new blueprint is 
Step-by-step explanation:
we know that
The scale of the original blueprint is

and
the width of the living room on the original blueprint is 6 inches
so
<em>Find the actual width of the living room, using proportion</em>

<em>Find the actual length of the living room, using proportion</em>

<em>Find the scale of the new blueprint</em>, divide the length of the living room on the new blueprint by the actual length of the living room

simplify
<em>Find the width of the living room in the new blueprint, using proportion</em>
