Jim wants to put carpet in 4 identical rooms. each room is 14ft by 20.5. ft. a roll of carpet will cover 2oo ft. how many rolls will he need

Find the total square footage of each room. The room will be a rectangle and finding the area of a rectangle is just the length times the width

area of rectangle = lw

area of each room = 14 x 20.5 = 287 ft^2

The 4 rooms each have the same square footage.

Total square footage of all rooms = 287 x 4  = 1148 ft^2

To find how many roles of carpet are needed, divide the footage needed to be covered by the footage per carpet

1148/200 = 5.74

You can't buy 5.74 of a carpet roll, so you will need 6 rolls :)

Hope I helped

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
