Question 971875
{{{l=5x+3}}}
{{{b=3x-2}}}
So, the perimeter = {{{2l+2b}}}
={{{2*(5x+3) + 2*(3x-2)}}}
={{{16x+2}}}         -----------(i)
And Area = {{{l*b}}}
={{{(5x+3)*(3x-2)}}}
={{{15x^2-x-6}}}---------------(ii)
If area = 230 ,then
{{{15x^2-x-6 = 230}}}
=> {{{15x^2-x-236 = 0}}}
=> {{{x=4}}} (x can't be neagative since breadth will become negative.
So the perimeter  = 16*4+2
= 66 cms
