Let the length and breadth of the rectangular field be ‘p’ metres and ‘q’ metres respectively Then, according to the question, 2 × (p + q) = 34 Or, (p + q) = 34/2 = 17…… (1) Also p × q = 60 We know, (p + q)2 = p2 + q2 + 2pq Or, p2 + q2 = 172 – 2 × 60 Or, p2 + q2 = 169 So, length of the diagonal of the rectangular field = √(length2 + breadth2) = √(p2 + q2) = √169 = 13 metres
