Question

7. The cost of fencing a rectangular park at * 28.50 per metre is 3648. Find its length and breadth if they are in a ratio 5:3.​

Answer 1

Answer:

180The length of fence used, in meters is (Rs3648)/(Rs28.5) = 7296/57 = 128. The perimeter of the rectangular park, in meters is 2(length + width) = 128, so in meters length + width = 128/2 = 64. length/width = 5/3 = (5x)/(3x) for any non-zero X. Let us say that length=5x and with=3x, and find x as a length in meters 5x + 3x = 64 meters (5+3)x = 64 meters 8x = 64 meters X = (64 meters)/8 = 8 meters.length + width = 128/2 = 64. length/width = 5/3 = (5x)/(3x) for any non-zero x. Let us say that length=5x and with=3x, and find x as a length in meters 5x + 3x = 64 meters (5+3)x = 64 meters 8x = 64 meters X = (64 meters)/8 = 8 meters. So, length 5x = 5(8 meters) = 40 meters, and width = 3x = 3(8 meters) = 24 meters.

Answer 2

Step-by-step explanation:

180The length of fence used, in meters is (Rs3648)/(Rs28.5) = 7296/57 = 128. The perimeter of the rectangular park, in meters is 2(length + width) = 128, so in meters length + width=128/2 = 64. length/width = 5/3 = (5x)/(3x) for any non-zero X. Let us say that length=5x and with=3x, and find x as a length in meters 5x + 3x = 64 meters (5+3)x = 64 meters 8x = 64 meters X = (64 meters)/8 = 8 meters.length + width = 128/2 = 64. length/width = 5/3 = (5x)/(3x) for any non-zero x. Let us say that length=5x and with=3x, and find x as a length in meters 5x + 3x = 64 meters (5+3)x = 64 meters 8x = 64 meters X = (64 meters)/8 = 8 meters. So, length 5x = 5(8 meters) = 40 meters, and width = 3x = 3(8 meters) = 24 meters.
