Question

find the length of wire required to fence a rectangle field with three round, whose length and breadth are 150 m and 80m respectively

Answer 1

perimeter of the rectangle field=2(l+b)
                               = 2*150+80
                                =2*230m
                                 =460m
 
therefore wire required to fence it three times=460*3 
                                                                      =1380 m
hence, 1380 m wire would be required to fence the rectangular field thrice!

Answer 2

$\large \bold{ \underline{ \underline{ \sf \: Answer : \: \: \: }}}$

$\to$ 1380 m

$\large \bold{ \underline{ \underline{ \sf \: Explaination : \: \: \: }}}$

Given ,

$\star$ Length = 150 m

$\star$ Breadth = 80 m

We know that ,

$\large \bold{ \fbox{ \fbox{ \sf \: Perimeter = 2( l + b ) \: }}}$

$\to \sf Perimeter = 2( 150+80) \\ \\ \to</p><p> \sf Perimeter = 2 \times 230 \\ \\ \sf \to</p><p>Perimeter = 460 \: m$

Therefore ,

Wire required to fence it = 460 × 3 i.e 1380

Hence , 1380 m wire would be required to fence the rectangular field thrice
