Question

the dimensions of rectangle is 12×8 then find the cost of fencing of the cost fpr 2 rs for meter

Answer 1

Here we have to find Perimeter because fencing is done on sides.


So perimeter = 2(l + b)
= 2(12 + 8)
= 2 × 20
= 40m



Now cost = 2rs per metre

So 40 metre cost = 2 × 40
= 80rupees



Hope it helps dear friend ☺️✌️✌️

Answer 2

Dimensions of rectangle = 12m × 8m
∴ Length of rectangle = 12m
   Breadth of rectangle = 8m
  
Perimeter of rectangle = 2 ( length + breadth )
                                    = 2( 12 + 8 )
                                    = 40 m

Cost of fencing = 2 Rs / m
 Total cost of fencing = 2 × 40
                                  = 80 Rs
