Question

A square piece of field has each side equal to 150m. If 3 layers of barbed wie has to be used to fence it, what is the length of the wire required? Also find the total cost of the wire if a metre of wire costs rupeese 2 ???/?

Answer 1

Answer:

Answer. Thus, length of wire required is 1800 meter.

Answer 2

$\huge\fcolorbox{red}{cyan}{₹\:3600}$

Step-by-step explanation:

First lets Find The Length of wire required :-

• 1 layer = perimeter Of Square piece

$\bf\color{purple}{Perimeter = 4 \times side} \\ => \bf{lets \: put \: the values } \\ => 4 \times 150 \\ => \boxed{600}$

Therefore the Wire Required for 1 layer = 600 m

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

$Wire\:Required\:For\:1\:layer = 600\:m \\ => Wire \: required\:for\:3\:layers = 600 \times 3 \\ => \boxed{1800}$

Therefore The Total Wire required is 1800 m

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Now Lets Calculate the Cost Of Wire :-

$Cost\:of\:1\:metre\:Wire = ₹\:2 \\ => So\:,\:The\:Cost\:1800\:m\:Wire = ₹\: 2 \: Times 1800 \\ => \boxed{3600}$

Therefore the Total cost Is ₹ 3600
