Please help me in math​

Answer 1

• 4x/3

Explanation:

Let the area of initial square is x, then shaded squares will have area as geometric sequence:

• x/4, x/16, x/64, ...

The first term is x, the common ratio is 1/4

Sum of infinite GP is:

• S = a/(1 - r)

By substituting values we get:

• S = x/(1 - 1/4) = x / (3/4) = 4x/3
