This question consists of two statements,namely,Assertion (A) and Reason (R).For selecting the correct answer,use the following code:

(a) Both Assertion (A) and Reason (R) are true and Reason (R) correct explanation of Assertion (A).

(b) Both Assertion (A) and Reason (R) are true but Reason (R) is not a correct explanation of Assertion (A).

The correct answer is :(a) /(b) /(c) /(d)

Solution

ANSWER:
(d) Assertion is false and Reason is true.
Clearly, reason (R) is true.
Assertion: Area of a parallelogram = base × height
⇒ AB × DE = AD × BF
⇒AD = (16 × 8) ÷ 10 = 12.8 cm
So, the assertion is false.

ANSWER: (d) Assertion is false and Reason is true. Clearly, reason (R) is true. Assertion: Area of a parallelogram = base × height ⇒ AB ×​ DE = AD × BF ⇒AD = (16 × 8) ÷ 10 = 12.8 cm So, the assertion is ​ false.

ANSWER:
(d) Assertion is false and Reason is true.
Clearly, reason (R) is true.
Assertion: Area of a parallelogram = base × height
⇒ AB × DE = AD × BF
⇒AD = (16 × 8) ÷ 10 = 12.8 cm
So, the assertion is false.
