Step-by-step explanation:

Soln. Length of the heptagonal side of the table cloth = 74 m

Perimeter of table = 74*6

= 444 m

Cost of lace per metre = Rs. 10

Cost of lace to be added at the borders of the table cloth = Perimeter of table cloth * The cost of lace per metre

= 444 * 10

= Rs. 4, 440

Hence the cost of lace at the rate of Rs. 10 per metre is Rs. 4, 440
