Cynthia Besch wants to buy a rug for a room that is 19 ft wide and 33 ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 275 square feet of carpeting. What dimensions should the rug​ have?



Answer :

The dimensions of the rug that Cynthia Besch should buy are 11 ft wide and 25 ft long, which gives an area of 275 ft².

How are the dimensions determined?

The dimensions of the rug include the width and the length.

Cynthia is budget-constrained to buy 275 ft² only.

When we factorize 275, we have 1, 5, 11, 25, 55, and 275.

The possible combinations of width and length to get 275 ft² and also ensure that a uniform strip of the floor is left around the rug are 11 ft and 25 ft.  This width and length are less than the room's width and length and satisfy the requirement for a uniform strip.

The strip from the room's width and length must be 8 ft each (from all sides).

Data and Calculations:

Width of room = 19 ft

Length of room = 33 ft

Area of room = 627 ft²

Dimensions:

Width of rug = 11 ft(19 - 8)

Length of rug = 25 ft (33 - 8)

Area = 275 ft² (11 x 25)

Thus, the dimensions of the rug that Cynthia Besch should buy are 11 ft wide and 25 ft long.
