The greatest horizontal length of the green section using the given greatest vertical length is less than 252 ft.
It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.
You want to make sure that the area of your green section is no more than 126 square feet, so you decide to draw your green section in the rectangle shown.
The greatest horizontal length (L) is 0.5 ft.
Then the greatest vertical length (W) will be
The area is given as
L × W < 126
Then we have
0.5 × W < 126
W < 252
