Show answer & explanation
Correct answer: D
Answer: 748 metre
Reason:
Let the length be 6x and the breadth be 5x.
Given the breadth is 34 m less than the length: 6x − 5x = 34, so x = 34.
Compute the dimensions: length = 6 × 34 = 204 m; breadth = 5 × 34 = 170 m.
Perimeter = 2 × (length + breadth) = 2 × (204 + 170) = 2 × 374 = 748 m.
Therefore the perimeter of the rectangular plot is 748 m.
