Question

the cost of fencing a rectangular field at rupees 3.50 per metre is rupees 595 if the length of field B 60 M find its breadth​

Answer 1

Answer:

Breadth = 25 m

Step-by-step explanation:

Cost of fencing a rectangular field per metre = Rs 3.50

Area of fenced field = Perimeter of rectangular field.

⇒ Perimeter = $\dfrac{595}{3.50}$

⇒ Perimeter = 170 m

We know that ;

Perimeter of rectangle = 2 (l + b)

⇒ 170 = 2 ( l + b )

⇒ 170 / 2 = ( 60 + b )

⇒ 60 + b = 85

⇒ b = 85 - 60

⇒ b = 25 m

Hence, the breadth of rectangular field is 25 m.

Answer 2

Answer

= 25 m

Step-by-step explanation:

Cost of fencing a rectangular field =  Rs 3.50/per metre

Area of fenced field = Perimeter of rectangular field

⇒ Perimeter = 595/3.50 = 170 m

Perimeter of rectangle = 2 (l + b)

⇒ 170 = 2 ( l + b )  

⇒ 170 / 2 = ( 60 + b )  

⇒ 60 + b = 85

⇒ b = 85 - 60

⇒ b = 25 m

therefore, the breadth of rectangular field is 25 m.
