Find area of the border :
--------------------------------------------------------
Area of the room = 22 x 25 = 550 ft²
Area of the rug = 238 ft²
Area of the border = 550 - 238 = 312 ft²
--------------------------------------------------------
Define y:
--------------------------------------------------------
Let the width be y.
--------------------------------------------------------
Find area of the border in term of y :
--------------------------------------------------------
The area of the border = 22y x 2 + 25y x 2 - 4y² = 94y - 4y²
*We need to take away 4y² because the 4 corners will be overlap twice if we don't.
--------------------------------------------------------
Solve y :
--------------------------------------------------------
94y - 4y² = 312
4y² - 94y + 312 = 0
2y² - 47y + 156 = 0
<span>(y - 4)(2y - 39) = 0
</span>y = 4 or y = 19.5
--------------------------------------------------------
Answer: The border can be 4 ft or 19.5 ft

$65 * 6 = $390 total monthly payments made
The downpayment made is $125, so the total
balance at the end is:
balance = $513 – ($125 + $390)
balance = - $2
<span>There is an excess of 2 dollars at the end.</span>
