Area of room = width * length = (2x-1)*(7x+3) = 14x2 + 6x - 7x - 3 = 14x2 - x - 3 sq feet

The floor of a travel trailer is in the shape of a rectangle The length of the trailer is 3x plus 8 feet and the width is x feet What is the length of the trailer if its area is 256 square feet?
'x' is equal to 8 feet. The length would be (3*8)+8= 32'.

What is linear dimension and give example?
Linear dimensions, or linear units, measure the distance between two points. Since two points define a line, the units of distance are sometimes called "linear" units or dimensions. Some linear units are centimeters and inches, meters and feet, kilometers and miles, to name a few.Area dimensions are two-dimensional and measure area. They are often, but not always, expressed as squares of linear dimensions: square inches or inches squared (in2), square feet or feet squared (ft2), and square meters or meters squared (m2). A rectangle that is six feet long by four feet wide, for example, has an area of 24 square feet (six linear feet times four linear feet).Examples of units of area that are not a square of a linear unit are the acre and hectare. There are others.Volume dimensions are three-dimensional and are expressed as the cube of linear units. A cube that measures 2 centimeters on each edge has a volume of 2 x 2 x 2 = 8 cubic centimeters.In the context of air travel (from AlaskaAir's contract of carriage):Maximum Outside Linear Dimensions means the sum of the greatest outside length plus the greatest outside width plus the greatest outside height.Read more: What_are_linear_dimensions

How do you calculate the square footage of a room if it has inches not just feet ex 10'6X12'8?
12 inches = 1 foot 10'6 = 10 feet plus 6/12 = 10.5 feet 12'8 = 12 feet plus 8/12 = 12.67 feet square feet = 10.5 x 12.67 = 133 square feet
How many linear feet to surround 1500 square feet of lawn?
Unfortunately, "It Depends" - - To determine square footage, you have to know whether the lawn is square, rectangular, circular, or some other shape. Assuming a rectangle (or square), the square footage is determined by multiplying the length by the width. Linear footage is determined by adding 2 times the length plus 2 times the width. If the lawn is a square, there is only one answer (as there is only one solution which will give 1500 square feet: length and width of 38.73-some odd decimal, meaning 2 times length and 2 times width gives a linear footage of some 154.92 feet). However, if the lawn is rectangular, there are an infinite number of answers. Giving three examples to show the range: 1) If the lawn is 50 feet long by 30 feet wide, that will give (50x30), or 1500 square feet of area and ([50x2]+[30x2]), or 160 linear feet. 2) If the lawn is 100 feet long by 15 feet wide, that will give (100x15), or 1500 square feet of area and ([100x2]+[15x2]), or 230 linear feet. 3) If the lawn is an alleyway in the middle of a big city and 1500 feet long by 1 foot wide, that will still give the required (1500x1), or 1500 square feet of area...but a whopping ([1500x2]+[1x2]), or 3002 linear feet around! (Note that the square gives the least linear footage possible for a rectangular-shaped lawn) Have fun figuring out circular, elliptoid, and other funny shaped lawns...
