1. Given : area of the field is 1296 sq.m and length of field is 12m

To Find :   total cost of wiring if it costs rupees 25 per meter.

Solution:

Area of field = Length  * width

area of the field is 1296 sq.m

Length = 12 m

width = ?

=> 1296 = 12 *  width

=> width = 108  m

Perimeter = 2 ( length + width )

= 2 ( 12 + 108)

= 2 ( 120)

= 240  m

total cost of wiring if it costs rupees 25 per meter. = 25 x 240

= 6000  Rs
