Question 628318
Sri Rangaman Chettanchadiyapuram Madhavan Iyer's flower Garden is now a square. If she enlarges it by increasing the width 1 meter and the length 3 metres, the area will be 19 square metres more than the present area. What is the length of a side now? 
------------------------
{{{(s + 1)*(s + 3) = s^2 + 19}}}
{{{s^2 + 4s + 3 = s^2 + 19}}}
4s = 16
s = 4
