The length of a rectangular plot is 20 metres more than its breadth.
The length of a rectangular plot is 20 metres more than its breadth. If the cost of fencing the plot @ Rs. 26.50 per metre is Rs. 5565, what is the length of the plot in metres?
Answer/Solution
210
Steps/Work
Let length of plot = L meters, then breadth = L - 20 meters
and perimeter = 2[L + L - 20] = [4L - 40] meters
[4L - 40] * 26.50 = 5565
[4L - 40] = 5565 / 26.50 = 210
4L = 250
L = 250/4= 62.5 meters.
Answer: D
and perimeter = 2[L + L - 20] = [4L - 40] meters
[4L - 40] * 26.50 = 5565
[4L - 40] = 5565 / 26.50 = 210
4L = 250
L = 250/4= 62.5 meters.
Answer: D
