A field in the form of a parallelogram has base 15 dam and altitude is 8 dam. find the cost of watering the field at 10 P per
square metre.
To find the cost of watering the field, we first need to calculate the area of the field.
The area of a parallelogram can be found by multiplying the base (b) by the altitude (h). In this case, the base is given as 15 dam and the altitude is given as 8 dam.
So, the area of the field can be calculated as:
Area = base x altitude
= 15 dam x 8 dam
= 120 square dam
Next, we need to convert the area from square dam to square meters.
1 dam = 10 meters
So, 1 square dam = (10 meters) x (10 meters) = 100 square meters
Therefore, the area of the field in square meters is:
120 square dam x 100 square meters/dam = 12000 square meters
Now that we have the area of the field in square meters, we can calculate the cost of watering.
The cost is given as 10 P (pence) per square meter.
So, the cost of watering the field can be calculated as:
Cost = area x cost per square meter
= 12000 square meters x 10 P/square meter
= 120,000 P
Therefore, the cost of watering the field at 10 P per square meter is 120,000 P.
since 1 dam = 10m, the cost is
150m * 80m * 10P/m^2 = ? P
