IF the side of a square is tripled,how many times its perimeter will be that of the original square.

Explanation

Solution : Let the side of the square be a cm.
Its permeter = 4`xx` a = 4a cm.
The length of side of new square = 3a cm.
Its perimeter 4 `xx` 3a =12a cm
Now, 12a =3 `xx`4a ...[From (1) and (2)]
Ans. The perimeter of the new square is three times the perimeter of the original square.
