The length of a rectangular plot is thrice its breadth. If the area of the rectangular plot is 7803 sq. mtr, what is the breadth of the rectangular plot ?

Answer: Option A

Let the breadth of the plot be x metres
Then, length of the plot = (3x) metres
x × 3x = 7803
⇒ 3x² = 7803
⇒ x² = 2601
⇒ x = $$\sqrt{2601}$$
⇒ x = 51 m
