Answer 2

Appropriate Question :

Find the cost of fencing a rectangular park of Length 450 m and breadth 300 m at the rate of Rs. 32 per meter.

Given :

• Dimensions of a rectangular park :-
• Length of the rectangular park = 450 m
• Breadth of the rectangular park = 300 m

To find :

• Cost of fencing the park

Solution :

Firstly, find the area of the rectangular park.

Using formula,

Area of rectangle = l × b

where,

• l = length of the rectangle
• b = breadth of the rectangle

Substituting the given values,

⇒ Area = 450 × 300

⇒ Area = 135,000

Area of the rectangular park = 13,000 m²

Cost of fencing 1 m² of the park = Rs. 32

Cost of fencing 13,000 m² of the park = 135,000 × 32 = Rs. 4,320,000

Cost of fencing the rectangular park = Rs. 4,320,000
