The length of a rectangle is 6 meters more than twice the with If the area of the rectangle is 140 square meters find the dimensions?
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.

What are the dimensions of a rectangle with area of 400 square meters?
The dimensions of a rectangle with an area of 400 square meters can vary, as multiple pairs of length and width can produce this area. For example, if the length is 20 meters, the width would be 20 meters (making it a square). Alternatively, if the length is 40 meters, the width would be 10 meters. Thus, any combination of length and width that multiplies to 400 will satisfy the area requirement.
