<PRE><B>Question 274788</B>
length of a rectangle field is 155m and its width is 125m find the cost of fencing at the rate of Rs 10 per meter and fielding at it the rate of Rs 15 per square meter.

solution:

to find the rate of fencing, you should find the perimeter of the rectangle.
2(l+b) 
2(155+125)
2*180
360m 

cost of fencing = 360*10
                = Rs 3600

now to find the cost of fielding, find the area
(l*b)
155*125
19375 square mtr

cost of fielding = 19375*15
                 = Rs 290625
