Answer 2

Answer:

The cost of putting a boundary wall around a rectangular plot is 4570 rupees.

Explanation:

Given that:

Length = 150 m;

Breadth = 79m 60 cm; = 79.5 cm;

and,

Perimeter of the rectangular plot = 2(L + B);

So,

Perimeter of the rectangular plot = 2( 150 + 79.5)

The perimeter of the rectangular plot  = 459 m;

and It is given that:

A 2m long stretch is left on one of the longer sides for entrance.

So,

The Length of the boundary wall = 459 - 2 = 457 m;

Now,

The cost of putting a boundary wall around a rectangular plot

= 457 × 10

= Rs. 4570

Therefore,

The cost of putting a boundary wall around a rectangular plot is

4570 rupees.
