Answer 1

Answer:

pls mark me as brainliest if you are satisfied

Step-by-step explanation:

length of the big square = 100 m

length of the small square = 5 m

Side of the smaller square = Side of the bigger square - 2(width of the path)

                                          = 100 - 2(5)

                                          = 90 m

Area of the path = (100)² - (90)² = 10000 - 8100 = 1900 sq m

Cost of cementing at the rate of Rs 250 per 10 m² = 250 x 190 = Rs 4750
