Answer 2

Answer:

275m, 100m

Step-by-step explanation:

Let the common ratio be x.

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

We know that perimeter of rectangular garden = 2(length + breadth).

= 2(11x + 4x)

= 2(15x)

= 30x.

Given that Cost of fencing the plot at the rate of rs.100 per metre is 75000.

100 * Perimeter = 75000

100 * 30x = 75000

3000x = 75000

x = 25.

So,

Length of rectangular plot = 11x = 275m

Breadth of rectangular plot = 4x = 100m

Hence, the dimensions of the plot are 275m and 100m respectively.
