Question

There is a lawn which is 20 2/9 m in length and 12 4/7 in breath

1.Find the number of fences required to surround the lawn if each fence covers 2 5/7 m of the field

2. Find the cost of moving the lawn at Rs 21/16 per m^2

Answer 1

Step-by-step explanation:

1 . Perimeter of lawn = 2(20 2/9 + 12 4/7 )

2×(182/9 + 88.7)

2× (32.79)

45.36 m^2

length of 1 fench = 2 7/5=2.714

so we need = 45.36 × 2.714

=123.10...

So we need 123 and 1 more with some little lenght.

2. Cost of 1m =21 /16 = 1.2..

123.10× 1 . 2

=147.72 rs
