Assertion (A): Length of the diagonal of a square field is 15√2 m. Cost of ploughing the field at ₹20 per m2 is ₹4,500. Reason (R): 1. A is true, R is false 2. A is false, R is true 3. Both A and R are true 4. Both A and R are false

Question

KnowledgeBoat · Accepted Answer

Diagonal length = m For square : Side = ⇒ Side = ⇒ Side = 15 m. Area = (side)2 = 152 = 225 m2. Cost of ploughing = ₹20 per m2 Total cost = Area × Cost per m2 = 225 × 20 = ₹4,500. ∴ Assertion (A) is true. By formula, ∴ Reason (R) is false. Assertion (A) is true, reason (R) is false. Hence, option 1 is the correct option.
