Answer 2

Given,

• Side of a square piece of ground = 75 m

To find,

• The cost of erecting a fence around it at Rs. 4 per meter

Solution,

A square piece of ground is 75 m long. The cost of erecting a fence around it at Rs. 4 per meter is Rs. 1200.

We can simply find the cost of erecting a fence around it at Rs. 4 per meter.

As we know that the fencing is done around the boundary of the square piece of ground, then we have to find the perimeter of the square piece of ground.

Perimeter of square = 4 * Side

The perimeter of a square piece of ground = 4 * 75

                                                                        = 300 m

Now, cost of fencing of 1 m around it = Rs. 4

         Cost of fencing 300 m around it = 4* 300

                                                                = Rs. 1200

Hence, a square piece of ground is 75 m long. The cost of erecting a fence around it at Rs. 4 per meter is 1200 m.
