Given Δ PQR ∼ Δ DEF.

Assertion (A): If area of Δ PQR : area of Δ DEF = 9 : 49, then the ratio of their corresponding medians is also 4 : 9.

Reason (R): For the similar triangles, the ratio of their corresponding sides is equal to the ratio of their corresponding medians.

1. Assertion (A) is true, but Reason (R) is false.

2. Assertion (A) is false, but Reason (R) is true.

3. Both Assertion (A) and Reason (R) are correct, and Reason (R) is the correct reason for Assertion (A).

4. Both Assertion (A) and Reason (R) are correct, and Reason (R) is incorrect reason for Assertion (A).

Given Δ ABC ∼ Δ DEF.

Assertion (A): If area of Δ ABC = 64 cm², area of Δ DEF = 49 cm² and BC = 4 cm, then EF is 7 cm.

Reason (R): The ratio of area of two similar triangle is equal to the ratio of square of their corresponding sides.

1. Assertion (A) is true, but Reason (R) is false.

2. Assertion (A) is false, but Reason (R) is true.

3. Both Assertion (A) and Reason (R) are correct, and Reason (R) is the correct reason for Assertion (A).

4. Both Assertion (A) and Reason (R) are correct, and Reason (R) is incorrect reason for Assertion (A).
