What is the side length of a regular octagon area is (9.68s square root 2+9.68) square meters?

Solution-

As we know the area of the regular octagon with side as a is,

Area = 2(1+√2)a²

Here the area given as 9.68√2 + 9.68 = 23.36

Equating both

⇒2(1+√2)a² = 23.36

⇒2×2.41×a² = 23.36

⇒a² = 23.36/4.82 = 4.84

⇒a = 2.2meter

Therefore the length of the side of the given octagon is 2.2 meter

i think the answer is b.

not 100% sure though.
