Let the length of the rectangular plot be 11x and breadth be 4x.

Rate of fencing per metre = ₹100

Total cost of fencing = ₹75000

Perimeter of the plot = 2(l + b)

= 2(11x + 4x) = 2 × 15x = 30x

Total amount of fencing = (30x × 100)

According to the question,

(30x × 100) = 75000

⇒ 3000x = 75000

⇒ x = $$\frac{75000}{3000}$$

⇒ x = 25

Length of the plot = 11x

= 11 × 25 = 275m

Breadth of the plot = 4 × 25

= 100 m.
