Answer:

The length of plot = 45 m

Step-by-step explanation:

Let the breadth of the plot be x m.

Then, the length of a plot = (x + 9) m

Area of a rectangle = l × b

Here,

l is the length of a rectangular plot.

b is the breadth of a rectangular plot.

Putting the values in the formula, we have:

  • 1620 = (x + 9) × x
  • 1620 = x² + 9x
  • x² + 9x - 1620 = 0
  • x² - 36x + 45x - 1620 = 0
  • x(x - 36) 45(x - 36) = 0
  • (x + 45) (x - 36) = 0

Now, finding the value of x

Take

  • x + 45 = 0
  • x = - 45

Now, take

  • x - 36 = 0
  • x = 36

Finally, finding the length of a rectangular plot.

  • The length of a rectangular plot = 36 + 9
  • The length of a rectangular plot = 45 m
