Answer:
Rs 740
Step-by-step explanation:
20m length for inner rectangle
15m width for inner rectangle
area of inner rectangle = 20x15 = 300 square metre
20+2 = 22m length for outer rectangle
15+2 = 17m width for outer rectangle
area of outer rectangle = 22x17 = 374 square metre
Area of strip = 374-300 = 74 square metre
Rate of levelling strip = 10x74 = 740
Rate = Rs 740
