An oblong piece of ground measures 19m 2.5dm by 12m 5dm. From the centre of each side a path 2m wide goes across to the centre of the opposite side. Find the cost of paving these paths at the rate of rs.1.32 per sq m?  Answers:	A) Rs. 43.6	B) Rs. 78.65	C) Rs 54.75	D) Rs. 344	E) Rs. 34.4
Area of path horizontal=20*192.5=

3850 dm^2   Area of path vertical=20*125= 
<gadget id="calculator">20*125</gadget>
<output>2_500</output>
2500 dm^2   Since center path is covered twice so total area=(3850+2500)-(20*20)= 
<gadget id="calculator">(3850+2500)-(20*20)</gadget>
<output>5_950</output>
5950 dm^2   total cost=1.32*59.5 m^2=78.54   ANSWER:Rs. 78.65
