  • A 507 sq. m. ✔ ✖
  • B 537 sq. m. ✔ ✖
  • C 519 sq. m. ✔ ✖
  • D 520 sq. m. ✔ ✖
Correct Answer: Option A

Explanation


Let the breath = x

So, the Length = 3x

Perimeter of a rectangle = 2 (Length + Breadth)
So, 2 (3x + x) = 106
      6x + 2x = 106
      8x = 106
       x = 104/8 = 13

Now, Breadth = 13, so, length = 13 * 3 = 39

So, its area = Length * Breadth
                     = 39 * 13 = 507 sq. m.
