please help,
a field is in the form of a parallelogram whose base is 420m and height is 3.6 dam. find the cost of watering at 10 ps per sq.m
To find the cost of watering the field, we first need to calculate the area of the field and then multiply it by the cost per square meter.
The formula to calculate the area of a parallelogram is:
Area = base * height
Given that the base of the parallelogram is 420m and the height is 3.6 dam (decameters), we need to convert the height to meters first.
1 decameter (dam) = 10 meters
So, the height of the parallelogram in meters is 3.6 dam * 10m/dam = 36 meters.
Now, we can calculate the area of the field:
Area = 420m * 36m = 15,120 square meters.
Finally, we can find the cost of watering by multiplying the area by the cost per square meter (10 ps per sq.m):
Cost of watering = 15,120 sq.m * 10 ps/sq.m = 151,200 ps (paise).
Therefore, the cost of watering the field at 10 ps per square meter is 1,51,200 ps.
