1.	A field is in the shape of a trapezium, its parallel sides are 40 m and 85 m and thedistance between the parate of 12/m2rallel sides is 12 m. Find the cost of ploughing the field at the
Answer» Let's take the parallel sides as 'a' = 40m and 'b' = 85m Here, Height of the trapezium = h = 38m So, as we know that area the area of a trapezium = {(a+b)h}÷2 Area of given trapezium = {(40+85)×12}÷2 = (125×12)÷2 = = 750 m² It is given that rate of cost of ploughing is = ₹12/m² So, Total cost of ploughing = 750*12 = ₹9000

Answer»

Let's take the parallel sides as 'a' = 40m

and 'b' = 85m

Here, Height of the trapezium = h = 38m

So, as we know that area the area of a trapezium = {(a+b)h}÷2

Area of given trapezium = {(40+85)×12}÷2

= (125×12)÷2

= 750 m²

It is given that rate of cost of ploughing is = ₹12/m²

So,

Total cost of ploughing = 750*12 = ₹9000
