Question

Find the cost of levelling it at 1.50 per square metre​

Answer 1

Cost of levelling =Rs.15 per square meter

Let A be the area of lawn.

Therefore,

Cost of levelling lawn =15×A=Rs.19,935(Given)

⇒A=

15

19935

=1329m

As we know that,

Area of square =a

2

Here a is the edge length of square.

Since, lawn is in square form.

Therefore,

Side length of square (a)=

A

=

1329

=36.45m

Perimeter of square =4a=4×36.45=145.82m

Now,

Cost of fencing =Rs.22 per meter

Therefore,

Cost of fencing lawn =22×145.82≈Rs.3208
