Cynthia Besch wants to buy a rug for a room that is 25 ft wide and 32 ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 588 square feet of carpeting. What dimensions should the rug​ have?

Well, Cynthia is in quite the hairy situation! Let's see if I can help her untangle this rug puzzle.

First, let's calculate the total area of the room by multiplying the length and width:

Area of the room = 25 ft * 32 ft = 800 square feet

Now, let's subtract the area that Cynthia wants to leave as a strip from the total area of the room:

Area of the strip = 800 ft² - 588 ft² = 212 ft²

Since the strip has a uniform width around the rug, we need to find the dimensions of the rug by subtracting twice the width of the strip from the total room dimensions:

Width of the rug = 25 ft - 2 * width of the strip
Length of the rug = 32 ft - 2 * width of the strip

Now, we have to solve two equations simultaneously:

Width of the rug * Length of the rug = Area of the strip
Width of the rug = 25 ft - 2 * width of the strip
Length of the rug = 32 ft - 2 * width of the strip

This seems like a job for a mathemagician! Give me a second to crunch the numbers and find the dimensions...

*Calculating... calculating... tick-tock...*

Ah-ha! The dimensions of the rug should be approximately 13.86 ft by 9.71 ft.

But remember, Cynthia! It's always important to measure twice and cut once. And if you cut twice, it might be time to switch to origami instead. Happy rug shopping!

To find the dimensions of the rug, we need to subtract the dimensions of the floor strip from the room dimensions.

Let's assume the width of the floor strip is 'x' ft.

The width of the rug will be: 25 ft - 2x ft (since there are two floor strips on the width)

The length of the rug will be: 32 ft - 2x ft (since there are two floor strips on the length)

To find the area of the rug, we multiply the width and length:

Area of the rug = (25 ft - 2x ft) * (32 ft - 2x ft)

Since Cynthia can afford to buy 588 square feet of carpeting, we can set up the following equation:

(25 ft - 2x ft) * (32 ft - 2x ft) = 588 sq ft

Expanding the equation:

800 ft^2 - 25x ft - 64x ft + 4x^2 ft^2 = 588 sq ft

Combining like terms:

4x^2 ft^2 - 89x ft + 212 ft^2 = 0

Now, we can solve this quadratic equation using factoring, completing the square, or the quadratic formula. For simplicity, let's use factoring.

Factoring the equation:

(2x ft - 53)(2x ft - 4) = 0

Setting each factor equal to zero:

2x ft - 53 = 0 or 2x ft - 4 = 0

Solving each equation:

2x ft = 53 or 2x ft = 4

x = 53/2 ft or x = 4/2 ft

x = 26.5 ft or x = 2 ft

Since the floor strip cannot be more than half the width or length, the only valid value is x = 2 ft.

Plugging x = 2 ft back into the equations for the rug dimensions:

Width of the rug = 25 ft - 2(2 ft) = 25 ft - 4 ft = 21 ft
Length of the rug = 32 ft - 2(2 ft) = 32 ft - 4 ft = 28 ft

Therefore, the dimensions of the rug should be 21 ft wide and 28 ft long.

To find the dimensions of the rug in this scenario, we can follow these steps:

1. Calculate the total area of the room:
Room area = width * length = 25 ft * 32 ft = 800 square feet

2. Determine the area of the floor strip that Cynthia wants to leave uncovered by the rug. Let's represent this strip's width as 'x' (uniform on all sides of the rug).
Area of the floor strip = (width - 2x) * (length - 2x)

3. Calculate the area of the rug:
Rug area = total area - area of the floor strip = Room area - Area of the floor strip = 800 square feet - Area of the floor strip

4. Set up an equation to solve for 'x':
Rug area = 588 square feet
588 = (width - 2x) * (length - 2x)

5. Solve the equation to find 'x':

Expand the equation:
588 = (25 - 2x) * (32 - 2x)

Simplify and put the equation into standard form:
588 = 800 - 109x + 4x^2

Rearrange to form a quadratic equation:
4x^2 - 109x + 800 - 588 = 0

Simplify further:
4x^2 - 109x + 212 = 0

Solve for 'x' by factoring, completing the square, or using the quadratic formula:
In this case, we can factor:
(4x - 53) (x - 4) = 0

So, we have two possible solutions:
4x - 53 = 0 -> 4x = 53 -> x = 13.25 ft
x - 4 = 0 -> x = 4 ft

6. Calculate the dimensions of the rug:
Since the rug should be smaller than the room, we choose the smaller value for 'x', which is 4 ft.
Width of the rug = width - 2x = 25 ft - 2 * 4 ft = 25 ft - 8 ft = 17 ft
Length of the rug = length - 2x = 32 ft - 2 * 4 ft = 32 ft - 8 ft = 24 ft

Therefore, the rug should have dimensions of 17 ft by 24 ft to allow for a uniform strip of floor around it.

(25 - x)(32 - x) = 588

x^2 - 57 x + 212 = 0

solve for x (the border width)

then find the length and width
... subtract twice the border from each room dimension
