Audrina's curtain company is making curtains for a local hotel. She wants each curtain to be 48 inches long. At the fabric store

yarga [219]

Answer:

Audrina needs 216 feet long fabric to make 54 curtains.

Step-by-step explanation:

Length of 1 curtain = 48 inches.

So, the length of 54 curtains = (48 x 54) inches

= 2592 inches.

So, total fabric needed to make 54 curtains = 2592 inches.

Now 1 inch = 0.0833 foot

So, 2592 inches = (2592 x 0.0833) feet

= 215 . 91 feet ≈ 216 feet

So, Audrina needs 216 feet long fabric to make 54 curtains.
