The length of a rectangular plot is 20metres more than its breadth . If he cost of fencing the plot @ 26.50 per metre is Rs. 5300, what is he length of the plot in metres ?
Let breadth = `x` meres, Then , length = `(x + 20)` meres.
perimeter = `(5300/26.50)` m = 200 m.
`:..` ` 2[(x + 20) + x] = 200`
`hArr 2x + 20 = 100`
`hArr 2x = 80` `hArr x = 40`
Hence , length = `x + 20 = 60` m.
