​

Answer 1

Answer:

Answer: Cost of framing is Rs. 6840.

Step-by-step explanation:    

Since we have given that

Length of mirror frame would be

20+2+2=24 cm

Width of mirror frame would be

15+2+2=19

Area of frame would be

length × breadth

24 × 19

= 456 cm^2

Cost per sq. Cm = Rs. 15

Total cost would be

456×15 = Rs. 6840

Hence, cost of framing is Rs. 6840.
