Question

The shape of a farm is like a quadrilateral The lengths of the sides are 35.62m, 45.6m, 38.38m, and 35.4m. If the owner wants to fence it with 3 strands of barbed wire, how many meters of barbed wire does he need?

Answer 1

Answer:

He will need 465 metres of barbed wire.

Step-by-step explanation:

Perimeter of the field = 35.62m + 45.6m + 38.38m + 35.4m = 155m

Fencing for one strand = 155m

Fencing for three strands = 155 * 3 = 465m

Answer 2

Step-by-step explanation:

Add all the sides to find perimeter :

$\implies$ $P=35.62+45.6+38.38+35.4$

$\implies$ $P=155.42m$

$\implies$ $155.42×3\:strands$

$\implies$ $466.26m$

466.26m of barbed wire is needed.
