Question

If the side of a square is tripled, how many times the perimeter of the first square will that of the new square be

Answer 1

Let the side of the square be $a$ units.

Therefore perimeter $=4a$ units

If the side is tripled i.e., it becomes $3a$ units

Then perimeter $4\times 3a=12a$ units

$\frac{Perimeteroffirstsquare}{Perimeterof2ndsqaure}=\frac{4a}{12a}=\frac{1}{3}$times
