Question

find the cost of fencing a rectangular field are in the ratio 5: 3 . If its perimeteris 128m , find the dimensions​

Answer 1

Step-by-step explanation:

Let the length of the rectangular field = 5x and breadth = 3x

2(length + breadth) = perimeter

2(5x + 3x) = 128m

2(8x) = 128m

16x = 128m

x = 128/16

x = 8m

hence the length = 5(8) = 40m and

breadth = 3(8) = 24m
