Convert inches to feet.

 1inch/2feet=6 inches/x    Solve of x   So x=6 inches (2feet/1 inch) So x=12 feet.

So for the other dimension 

1inch/2 feet= 7.5 inches/x    Solve for x So x=7.5 inches(2feet/1inch ) So x=15ft.

Assuming the room is a rectangle. Then the area is (12 feet) (15 feet)= 180 square feet
