How to calculate the area of a large space. D = a 2 × (1 + 5) \text{d}=\dfrac{a} {2}\times\left(1 + \sqrt{5}\right) d = 2 a × (1 + 5 ) in this equation: For example, if the side of a pool with the shape of an octagon is 10 yards, its area is then 2 · (1 + √2) · side 2 = 4.828427 · 10 2 = 4.828427 · 100 = 482.8427 square yards.
