Question

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

Answer 1

I80The 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.

So, length = 5x = 5(8 meters) = 40 meters, and

width = 3x = 3(8 meters) = 24 meters.
