Question

Find the cost of fencing a rectangular park of length 500 cm and breadth 750 cm at the rate of Rs. 12 per metre.

• A. Rs. 1500
• B. Rs. 3000
• C. Rs. 300
• D. Rs. 250

Answer 1

The correct option is C Rs. 300

We know,
100 cm = 1 m
Length of the rectangular park = 500 cm = 5 m
Breadth of the rectangular park = 750 cm = 7.5 m
To calculate the cost of fencing we require perimeter value.
Perimeter of the rectangle = 2 × (length + breadth)
= 2 × (5 m + 7.5 m)
= 2 × (12.5 m) = 25 m

Cost of fencing 1m of park = Rs. 12
Therefore, the total cost of fencing the park
= Rs. (12 × 25) = Rs. 300
