Question

how much wire is needed for fence a field whose area is 63sq.m and breadth is 7m
​

Answer 1

Step-by-step explanation:

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!

Hope it helps.:)-

Answer 2

Answer:

32m long wire is used to fence the field

Step-by-step explanation:

Given area =63 sq.m

breadth(b) =7m

Area=lb

63=7l

l=63/7

l=9

Length =9m

Perimeter =2(l+b)=2(9+7)=2(16)=32m
