xy=48


Length is x and breadth is y.


If the length and breadth be increased by 1 metre each the area is increased by 15 square metres.

{{{(x+1)(y+1)-xy=15}}}
{{{xy+x+y+1-xy=15}}}
{{{xy-xy+x+y=15}}}
{{{x+y=15}}}


Your system of two equations is now {{{system(xy=48,x+y=15)}}}, which you may already know how to solve.
