the above triangle has all sides equal to 1 and is bigger in area than any triangle with each side less than 1 its area is 1 * 0.5 = 0.5 square feet that proves it

OpenStudy (whpalmer4):

Formula for the area of a triangle is \[A = \frac{1}{2}bh\]Even if we assume the height could be \(1 \text{ ft}\), which it clearly cannot be, the maximum area we could get would be \[A = \frac{1}{2}(1\text{ ft})(1\text{ ft}) = \frac{1}{2}\text{ ft}^2\]and that is much less than \(100 \text{ ft}^2\)!
