Question 82

What will be the cost of gardening 1 metre broad boundary around a rectangular plot having perimeter of 340 meters at the rate of Rs 10 per square metre?

Solution

here the cost of boundary making = 10 per sqmt

Total area to be boundaried = 2 L + 2B + (1×4)...(1)

It is given that perimeter of rectangle is 340 m

So 2(L + B ) = 340....(2)

From equation 1 and 2

Total area to be boundaried = 344 sq mtr

Cost of boundaring 344 sq mtr area = 344 × 10 = Rs 3440
