rectangular shape and the other is in square shape and combines them to make a single new plot.

What will be the side of the square when the length of the rectangular plot is 15m.Solution
ATQ, we can say that  Given the Length of rectangular plot is = 15m  Breadth of rectangular plot = side of square plot = 'p'  Now, 2(p + 15) + 2p = 390/5  2p + 30 + 2p = 78  4p = 48  p = 12m
