This question requires us to solve an infinite GP
As we can see the first unit is 16 wide, then 8, then 4 and so on; this can be written as
∞
(64 used as 16*4 = 64 is the area of the first rectangle)
We have ∞
where a is the first term and r is the common ratio of the GP for summing an infinite GP.
here we have
Therefore
∞
