A rectangular plot is half as long again as it is board and is area is `2/3` hectares , Then is length is :
Let breadth = `x` metres. Then , length = `(3/2 x)` metres.
Area = `(2/3 xx 10000) m^2`
`:.` `2/3 x xx x = 2/3 xx 10000`
`hArr x^2 = 4/9 xx 10000` `hArr x = 2/3 xx 100`
`:.` Length = `3/2 x = (3/2 xx 2/3 xx 100)`m = 100 m.
