Question

A triangular field has sides 200 m, 280 m and 330 m long. How
many metres of wire is required to fence the field?​

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

perimeter of the field is-(200+280+330)=810m
