Question

Jeans bedroom is 11 feet by 13 feet. She has chosen a carpet which cost $33.35 per square yard. This includes installation. Determine her cost to carpet her room

Answer 1

Answer:  $489.13

===========================================================

Work Shown:

1 yard = 3 feet

1/3 yard = 1 foot .... divide both sides by 3

1 ft = 1/3 yard

11 ft = 11/3 yard ... multiply both sides by 11

13 ft = 13/3 yard ... same idea, but now with 13

-----

area in square yards = (11/3)*(13/3) = 132/9 square yards

Multiply this area with the cost per square yard ($33.35) to get

(132/9)*33.35 = 489.133333

Rounding to the nearest penny, we get $489.13
