Answer» Answer: Length of the lawn = 50 m Breadth of the lawn = 35 m Area of the lawn = (50 × 35) m² = 1750 m² Length of lawn including the path = [50 + (2 + 2)] m = 54 CM Breadth of the lawn including the path = [35 + (2 + 2)] m = 39 m Area of the lawn including the path = 54 × 39 m² = 2106 m² Therefore, area of the path = (2106 - 1750) m² = 356 m² For 1 m², the cost of turfing the path = $ 3 For 356 m², the cost of turfing the path = $3 × 356 = $1068 |
