Given :-

• Sheetal wants to fence the garden in front of her house , on four sides with length 30m and breadth 20 m.  

To Find :-

• Find the cost of fencing at the rate of Rs 120 per meter

Solution :-

~Here, we’re given that Sheetal wants to fence her rectangular garden with length 30 m , breadth 20 m and we need to find the cost of fencing at the rate of Rs 120 per meter. Firstly we’ll find the perimeter of the garden and then multiply the perimeter with the cost per meter to find the cost of fencing.

_____________

As we know that ,

★   Perimeter of rectangle = 2( l + b )

Where,

• l is length  
• b is breadth  

Finding the perimeter of garden :-

⟶ 2( 30m + 20m )  

⟶ 2( 50m )  

⟶ 2 × 50m  

⟶ 100m  

Finding the cost of fencing :-

⟶ Rs 120 × 100  

⟶ Rs 12,000

_____________

Hence,  

• Cost of fencing the garden will be Rs 12,000
