Answer---> Breadth = 9m

Step-by-step explanation:

Given---> The total cost of levelling rectangular field is 7200 rupees if the cost of levelling is rupees 40per square meter and length of the rectangular field is 20 m

To find---> Breadth of the field

Solution---> ATQ,

Total cost of levelling = 7200 rupees

Cost of leveliing = 40 rupees / m²

We know that , we get area of rectangle dividing total cost of levelling by cost per square m .

Area of field

= Total cost / cost per m²

= 7200 / 40

= 720 / 4

= 180 m²

We know that,

area of rectangular field = length × breadth

=> 180 = 20 × breadth

=> breadth = 180 / 20

=> breadth = 9 m

Area of field

= Total cost / cost per m²
