nvm that tho... when the answer isn't exact.. I'm 75% not sure about it.. -.-
the distance between the sides is 15cm or 15m
hmmm...
Rupees is the currency of INDIA
oh okay.. lol I don't know that tho.. well, I'm a foreigner ☺

Considering the distance between parallel sides (h) = 15 METERS
Let one parallel side of the trapezoid be a = 10m
Another parallel side be b = 25m
The height that is the distance between the parallel sides = 15m
Area = [(a+b)/2]h
=  [(10+25)/2 × 15] m²
=  [35/2 × 15] m²
=  [17.5 × 15]m²
=  262.5 m²
Cost of watering one m² area = Rs 4
Cost of watering 262.5 m² area = Rs 1050
you are welcm
