Answer» N: The breadth of a rectangular field is TWICE its length. If the area of the field is 1058 m, FIND the COST of fencing it at 35 per mFOLLOW THE IMAGE ANSWER EXPLANATION: Consider length of the rectangular field = l meters,∵ Breadth is twice its length.So, width = 2l,Thus, area = length × widthAccording to the QUESTION,NEGATIVE value will not consider because side can not be negative That is,breadth = 2(23) = 46Hence, perimeter of the field = 2(length + breadth) = 2(23+46) = 2(69) = 138 metersIf cost of fencing for 1 meter = 35 rupeesThen the cost of fencing 138 meters = 138 × 35 = 4830 rupees
