Answer 1

→ The cost of the required lace is  20.8 Rs

Step-by-step explanation:

→ Side of cushion = 65 cm

→ Perimeter = 4 x  side

→ Perimeter = 4 x 65

                 = 260 cm

→ Cost of lace per meter =  8  Rs

                              = 8 x 260/100

→ Total cost of lace  = 8 x 2.6

                               = 20.8 Rs

• Thus the cost of the required lace is  20.8 Rs.
