Question

the cost of levelling a square lawn at Rs 15 per square metre is Rs 1900 935 find the cost of fencing the lawn at Rs 22 per metre

Answer 1

The Area of the lawn is :

1900935/15 = 126729m²

Since this is a square :

Length = Width

The length is thus :

√126729 = 355.99m

The Perimeter is :

355.99 × 4 = 1423.96m

22 × 1423.96 = Rs 31327.12
