Cynthia Besch wants to buy a rug for a room that is 22 ft wide and 27 ft long.
She wants to leave a uniform strip of floor around the rug.
She can afford to buy 266 square feet of carpeting. What dimensions should the rug have?
~~~~~~~~~~~~~~~~~~~~~
(27-2x)*(22-2x) = 266,
where x is the wide of the uniform strip.
Simplify:
= 266, or
= 0.
Solve this quadratic equation. Use the quadratic formula.
Then find the dimensions 27-2x (length) and 22-2x (width).
