Question

The ratio of length and width of a re
a rectangular floor is 5 : 6. If the perimeter of the field is 286 m,
find the length and width.​

Answer 1

Answer:

286=2(x+y)

x+y=143

x=length

y=width

x/y=5/6

x=5y/6

5y/6+y=143

(5y+6y)/6=143

11y=143×6

11y=858

y=858/11

y=78

x=(5×78)/6

x=390/6

x=65
