Question

The three sides of a triangular field are 42 m, 38 m and 47 m respectively. A fourfold wire fence is to
put around the field. Find the lenth of the wire.
​

Answer 1

${Perimeter of\; the \;triangular \;field}$

42+38+47=127 m

Fourfold= 127*4= 508m

Answer 2

Step-by-step explanation:

Number of the three sided triangular field 42m,38m and 47m respectively.

The Perimeter of the triangular field= (42+38+47)m

=127m.

Now for the length of the wire we need area of the triangular field.

127*3= 381m^2.
