Answer 1

$\huge\underline\blue{AnSweR}$...

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 =

⇒ 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

Step-by-step explanation:

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 =

⇒ 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.
