A rectangular park with a 3:2 side ratio has a 3750 sq m area. Find the fencing expense at 50 ps per meter_______?
Show answer Hide answer
Answer: C. Rs.125
Explanation
The correct answer is one hundred twenty-five rupees for the total fencing expense. Letting sides be three x and two x gives an area equation of six x squared equal to thirty-seven fifty. Solving for x gives twenty-five, making sides seventy-five and fifty with perimeter two hundred fifty meters. Area of a rectangle equals length multiplied by width. Perimeter of a rectangle equals two multiplied by the sum of length and width. Fencing expense is calculated by multiplying the perimeter by the cost per meter.
Land landscaping and property fencing require precise area and perimeter calculations. Civil engineering projects estimate material costs based on perimeter boundary measurements. Real estate development uses rectangular dimension ratios for park and lot design. Option A overestimates the fencing expense by using an incorrect perimeter calculation. Option B underestimates the total cost by miscalculating the side length multiplier. Option D results from an arithmetic error during the cost per meter multiplication.
