Answer: 32 room
Step-by-step explanation:

<u>If 1 room = 7.75 yd of carpet ⇒ x rooms = 250 yd of carpet</u>
Use proportions & cross-multiply to solve:

So 250 yd of carpet can cover about 32 rooms.
60 × 100
Since the formula for area of a rectangle is length × width, multiplying the sides will get you the area.
