8.33 feet/minute

Step-by-step explanation:

We are given a measurement as 100 inches per minute

We are asked to convert this into feet per minute

Let us check the units

first one is in inches per minute

and second is in feet per minute

Since per minute remains the same for both, it is sufficient if we convert inches to feet

Conversion factor = 12 inches = 1 foot

Hence 100 inches = 100/12 = 8.33 feet

SO answer is

8.33 feet/minute

Width of the rug = x feet

Length of the rug = (x + 4) feet

Step-by-step explanation:

Let

Width of the rug = x feet

The rug is 4 feet longer than it is wide.

Length of the rug = (x + 4) feet

For instance, to find the area of the rug

Area of a rectangular rug = length × width

= (x + 4) * x

= x² + 4x

Area of a rectangular rug = x² + 4x

To find the perimeter of the rug

Perimeter of the rectangular rug = 2(length + width)

= 2{(x + 4) + x}

= 2(x + 4 + x)

= 2(2x + 4)

= 4x + 8

Perimeter of the rectangular rug = 4x + 8
