Question
The perimeter of a rectangular field is 34 metres and
its area is 60 m2 . What is the length of the diagonal of this field?Solution
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
