It is the special case of rectangle where all sides have same length, which we denote a. There is formula for surface area of rectangle with side a Thus
we can use
3+2*(sqrt(3)*sqrt(5)+5
now we can use and and we get
=
=
= which is around 11.873
If you are interested in higher mathematics, area of rectangle can also be computed using definite integral where a is constant function and integration bounds define left and right side, in our case it would be = F(b)-F(a) = whic leads to same result.
