Answer» Length of the big square = 100 mlength of the small square = 5 mSide of the smaller square = Side of the bigger square - 2(width of the path) = 100 - 2(5) = 90 mArea 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 47500 |
