Step-by-step explanation:

Area of rectangle = Length×Breadth

= 125 m×75 m

= 9375 m²

.

Perimeter of Rectangle = 2(l+b)

= 2(125 m+75 m)

= 2(200 m)

= 400 m

.

As told in question we have to find the cost of fencing. And obviously we will fence the field on its border. So, we multiply the cost of fencing with the perimeter.

.

Cost of fencing = ₹5 × 400

= ₹,2000

.

AnswEr :

  • We are provided a rectangular field whose Length (l) is 125 m and Breadth (b) is 75 m. We need to find the area of rectangle first and second we need to find the perimeter of rectangle and last we need to find the the cost of fencing it at the rate of rupees 5 per m. So, let's solve it :

A R E A⠀O F⠀R E C T A N G L E :

↠ Area of rectangle = Length × Breadth

↠ Area of rectangle = 125 × 75

Area of rectangle = 9,375 m²

The area of rectangle is 9,375 .

P E R I M E T E R O F R E C T A N G L E :

↠ Perimeter of rectangle = 2(Length + Breadth)

↠ Perimeter of rectangle = 2(125 + 75)

↠ Perimeter of rectangle = 2(125 + 75)

↠ Perimeter of rectangle = 2 × 200

Perimeter of rectangle = 400 m

∴ The Perimeter of rectangle is 400 m.

━━━━━━━━━━━━━━━━━━━━━━━━

C O S T O F F E N C I N G :

↠Cost of fencing 1 m = Rs. 5

↠Cost of fencing 400 m = 5 × 400

↠Cost of fencing 400 m = Rs. 2,000

∴ The cost of fencing 400 m field is Rs. 2,000 .

━━━━━━━━━━━━━━━━━━━━━━━━

◗ Area of Rectangle = 9,375 m²

◗ Perimeter of Rectangle = 400 m

◗ Cost of fencing 400 m field = Rs. 2,000
