Designate the length and width in meters by l and w respectively. Then, ,from the problem statement, l = 6 + 2w and l X w = 140. Substituting the first of these equations into the second yields w(6 + 2w) = 140, or, rearranging into standard form, 2w2 + 6w - 140 = 0; dividing by 2 gives w2 + 3 w - 70 = 0. This can be factored into (w-7)(w+10) = 0, which is true for either w = -10 or w = 7. A real rectangle, however, can not have a negative width; therefore, w = 7 and l = 20.

Length = 9 Width = 9 Your rectangle is a square.
How much square ins is a rectangle?
Without the dimensions, we won't be able to tell. The area of a rectangle is the length times the width. If those dimensions are in inches, the area will be in square inches.
What is the area of a rectangle that is 9 meters long and 8 meters wide?
The area of a rectangle is simply the length times the width. If the length and width are in meters, the area, of course, will be in square meters.
The area of a rectangle is 117 square meters. The width is 9 meters.What is the length of the rectangle?
If the area is 117 square meters and the width is 9 meters we can find the length by dividing: 117 / 9 = 13 The length is 13 meters
If the area of a rectangle is 11.5 square meters what are the dimensions?
You can't tell. The area doesn't tell you the dimensions. There are an infinite number of possible pairs of length/width measurements. The only thing you know for sure is that whatever the length and width are, you get 11.5 when you multiply them.
