Answer by srinivas.g(540) (Show Source): You can put this solution on YOUR website!
let width of plot of land be x meters
the length is 8 times its width
hence length = 8*x
=8x
perimeter of land = 40 m
plot is in shape of rectangle
perimeter of plot (rectangle) =2(length+width)

40 =2(9x)
40 = 18 x
divide with 18 on both sides

hence width (x)= 20/9
area = length* width
=
=
but x= 20/9
area =
=
=
result: area of plot of the land = 39.5 m^2
