Question

The length and breadth of a rectangular garden are 12 and 9 meters respectively and the total length of the wire brought for fencing the garden is 19metres will the wire length be sufficient to fence the garden? Estimate​

Answer 1

the perimeter of the garden = 2(l+b)

=2(12+9)

=42 metres

But we have only 19 metres of wire..

hence the wire is not sufficient

hope it helps

Answer 2

the perimeter of garden=2×(l+b)

2(12+9)

2(21)

2×21

42

19meter wire is not sufficient for this garden
