Question

The perimeter of a rectangle is 80 metre and its length is one metre more than twice the breadth. What are its length and breadth?

Answer 1

If x be the breadth, Then length = 2x + 1

2 (x + 2x + 1) = 80

2(3x + 1) = 80

6x + 2 = 80

6x = 80 – 2

x = \(\frac{80-2}{6}\) = 13.

breadth = 13 metre

Length = 2 × 13 + 1 = 27 metre
