If a person posts questions on yahoo answers to make their homework, how long will it take until they get caught?
If they are
a) too unconcerned to understand the actual point of the lesson in the first place
b) more aimed at current personal success than the future

If the cleaners charge 10 cents per square foot, then that’s 90 cents per sq. yard. (There’s 9 sq. ft. in a sq. yd.)
The area of the room is w yards by 1 yard or w sq. yards.
The cost will be the price per sq. yard ($.90) times the number of sq. yards, or
$.90w

Laura’s answer looks good, but she misunderstood one detail in the statement of the problem. The length of the room is not 1 (one) yard, it is l (the lower-case letter l) yards.

People should pay attention to Laura’s answers. She’s good. The important point in her answer is that there are 9 (not 3) square feet in one square yard.

ELAINE, everytime u ask a question I will surely answer with the statement “do ur own homework”.

W x l = wl sq.yards * 3 ft/yard = wl * 3 sq feet

(wl * 3 sq feet) * $0.10 = your answer

1 squair foot cost 10ct = $0.10

The area is 3w feet x 3L feet = 9wL squair feet

So 9wl squair feet costs 9wl x 0,10$ = $0,90x w x L.

width times length is total square yards, multiply this sum times 3 as there are 3 feet in a yard. This will be total square feet times .10

Convert to feet:

Room length = 3l

Room width = 3w

Room area = 3l x 3w = 9lw

Therefore cost = 9lw x 10c = 90lw.
