Discussion

Explanation:

Since, the side of each successive triangle is half, area of each successive triangle will be 1/4th i.e., the area of successive triangles will form an infinite G.P. with a common ratio 1/4.

∴ Total Area = A + A/4 + A/ 16 + … ∞

⇒ Total area = A/(1 - 1/4) = 4A/3

Hence, option (b).
