Problema Solution
She wants to buy a rug for a room that is 17 feet wide and 22 feet long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 176 square feet of carpeting. What dimensions should the rug have?
Answer provided by our tutors
The width of strip is x
So the equation is
(17-2x)(22-2x)= 176
So
x = 3
So the dimension is 11 feet wide and 16 feet long
